The hot fix installed ok and your tests pass, but compilation had a 
(probably insignificant) warning:

fastthread.c: In function �wait_condvar�:
fastthread.c:626: warning: passing argument 1 of �rb_ensure� from 
incompatible pointer type

This is gcc 4.1.2 on linux.

Do you happen to have a test case that reproduces the problems in the 
pre 1.0?

Is there something ruby code can easily do (easier than running the test 
case, that is) to detect whether it is running with the patched 
fastthread or the buggy one?
