This is not a problem with the stop-the-world mechanisms. They work
fine. I've stress-tested them heavily and not seen a problem in a
long time. My recent changes just made it clearer what was going on
(and fixed the bug I introduced last week that you ended up backing
out). If you look at the stack traces, no thread is in stop-the-world
code.
I have a sneaking recollection of needing to configure some property
of my X server on Darwin, way back when. I've tried searching the old
mail logs to see if I can dig up a reference but the Zope archives are
no longer on Elegosoft.com. What to do?
