Thanks for the pointer.  We were mistakenly redirecting pthread
functions not only in libguile, but also for our users.  I have fixed
that, and that helps this issue.

In addition, we were not calling GC_allow_register_threads().  I changed
to do so, and now the code in the original report (both with and without
GC_INIT in the main thread) works.

However it is now leaking memory.  I cannot reproduce the issue with
just libgc though, so it must be a Guile problem.

Thanks for the help!

Andy
