We've been running VMs with these changes[*] and they have fixed the 
Linux problems that we had. As an aside, one thing that we ran into (and 
that I just fixed a couple of days ago) is the effect that Delay in 
Squeak is not safe. Much of the manipulation of the Delay internal 
structures (SuspendedDelay and friends) happens from the calling process 
and if that calling process gets killed things go south quickly. 
Unfortunately, you won't ever run into this unless you run a server 
(because you won't ever get "truly asynchronous" interrupts to cause 
this to happen) which makes it all but impossible to recreate this 
problem on a single machine.

[*] Yours plus John's IGC fix which turned out to be important.
