Sounds plausible.  Is that what's actually happening, other thread
deadlocked waiting for rendezvous?

There's various places in the guile core which block without doing
"leave guile".  Not sure how those bits are meant to work.
guile-devel might be the place to take this up.

Probably better with bits in the g_thread_init funcs (which are
currently just the pthreads funcs direct).  I think they're supposed
to be the only places gtk/gdk/glib block.
