I've gotten the kernel to lock up hard when running one of
the ACE tests (MT_SOCK_Test), but I don't think it's KSE
related.  I'm on a UP system.  Most of the time that specific
test works fine, though.

All of the ACE tests have been tested with libkse on both
SMP and UP systems.  KDE and even mozilla work fine with
libkse (although libkse needs a patch to work around rtld-elf
not being thread-safe for mozilla to work).
