Subject: error in pthreads implementation?

Cancellation points haven't been implemented beyond a set of defines to
allow programs to compile... It's on my rather extensive todo list
though :]. I suspect that you may need them fully functional for java
:[. Unfortunately I don't have a timeframe for when I'll get time to
implement them, but I'm more than willing to proivde guidance if you are
interested in getting cancellation points extant.
