Is it a bug to use pthreads?
Having "trivially detectable buffer overruns" sounds like a completely
different issue than not being able to load libpthread, or are they related

How did those modules work pre-6.0?  I thought pthreads wouldn't work
at all when loaded through dlopen because libc would have initialized 
in non-threaded mode at process startup.
