Tim, have you looked at doing something in the millisecond clock call?  
In the past I've thought of that because it gets called a lot as a  
result of all the clock watching that happens all over the place either  
from the VM, or from Smalltalk code. Lately I've consider added a  
heartbeat call
to checkForInterrupts, then again that does call the millisecond clock  

I've looked into this area because of issues with aioPoll() and how  
socket interrupts are serviced, if you recall there was
concern last fall about how fast the mac carbon vm services socket  
listen events for seaside.
