[M3devel] AMD64_FREEBSD problems with current RC from m3 site

[Mika Nystrom]

More details about the "catatonic" case.  It's pretty bad.  Even ctrl-\
won't wake it up properly.  Ctrl-\ is supposed to cause the program to
abort and dump core.  It does nothing to my program now!  And I think
I've "lost threads" before, too.

Btw,

I'm happy to help debug if someone can give me some pointers...
