[squeak-dev] trunk and new vm etiquette

I only ever upgrade my VM if something breaks or if I am asked to. So
if you'd post a message with something like "Please upgrade your VM"
in the subject line to the list once you push the changes to Trunk,
that would be great for me!
Concerning the time span: in an ideal world I would say "as soon as
the CI is green", but I have my doubts that this will be enough for
Squeak. Assuming that you use the new VM immediately and frequently
(or anyone else does), I think a day of work up to a week after the VM
changes is fine. Or as soon as you are confident about it, however you
measure that. ;-)

The new replacement, which allows two methods (at:[put:]) in FloatArray to relace four methods (Float32Array>>at:[put:] & Float64Array>>at:[put:]) are some 5 to 10 times faster than the plugin methods. The issue is when to publish the corrections to trunk.

> Is it OK if I push the fixes to FloatArray and subclasses in a week? Do people using trunk keep an eye on the CI builds and upgrade, or would they appreciate a heads up? If so, as soon as the AppVeyor builds succeed for CogVM source as per VMMaker.oscog-eem.2778, I'll let you know and ask that you upgrade your VM.
