Yes, thanks, well that was the original idea for Smalltalk processSuspensionUnblocks to answer about the behavior of the primitiveSuspend #88; which was before the primitives #568 and #578 were introduced. (And which was when I wrote the tests using this original
logic). However that approach ran into problems with some existing implementations (e.g. Virtend) and as a result the two new primitives were introduced (#568 and #578) - and apparently the logic of what Smalltalk processSuspensionUnblocks answers about changed.
Since then I haven't heard from Eliot about his plans how to proceed with the new suspend semantics or whether this is it :)</p>
<p class="MsoNormal" style="margin-left:4.8pt">
</p>
<p class="MsoNormal" style="margin-left:4.8pt">
In case this is still WIP I'd quite like an approach similar to Smalltalk processPreemptionYields - you'd set Smalltalk processSuspensionUnblocks true or false depending on how you want the VM to behave and the VM would use the right semantics (unless this
is too naive :) ).</p>
<p class="MsoNormal" style="margin-left:4.8pt">
</p>
<p class="MsoNormal" style="margin-left:4.8pt">
Regarding the tests failing with the newest VM:</p>
<p class="MsoNormal" style="margin-left:4.8pt">
testAtomicSuspend - we can remove this updated version and leave the existing one for the moment</p>
<p class="MsoNormal" style="margin-left:4.8pt">
testRevisedSuspendExpectations - we can leave this one out too</p>
<p class="MsoNormal" style="margin-left:4.8pt">
testTerminateBlockedInNestedEnsure1 - I'll take a look at these two and try to adjust the logic</p>
<p class="MsoNormal" style="margin-left:4.8pt">
testTerminateBlockedInNestedEnsure2</p>
<p class="MsoNormal" style="margin-left:4.8pt">
</p>
<p class="MsoNormal" style="margin-left:4.8pt">
All remaining test in KernelTests-jar.421 work as intended.</p>

Yes, they are supposed to fail at the moment so I suggest to make them expected failures/feature requests. However there's a stupid bug in both I’ve fixed now: they were indeed supposed to fail the following assertion:

However, there's another issue regarding the revised #suspend semantics Eliot has been working on. I've updated the process tests in KernelTests-jar.421 to test both the old and the new #suspend semantics. The two semantics should be distinguishable via Smalltalk
processSuspensionUnblocks flag answering true in case of the old semantics and false in case of the revised one; my updated tests use this logic. However, unfortunately the latest VM answers "false" but uses the OLD suspend semantics in #suspend prim 88.
</p>
<p class="MsoNormal" style="margin-left:19.2pt">
</p>
<p class="MsoNormal" style="margin-left:19.2pt">
So I'm surprised you haven't observed more tests failing due to the new suspend semantics... What VM have you used – an older one? I'm on the latest trunk's VM 3183. And what is the answer of Smalltalk processSuspensionUnblocks? :) I'm utterly confused...

<p class="MsoNormal" style="margin-left:19.2pt">
Hi Eliot - I may be confused here but if the current VM uses the old #suspend prim 88 semantics, shouldn't ```Smalltalk processSuspensionUnblocks``` answer true?</p>
