I tried it and temacs runs OK.  However, it seems that the mutex 
initialization is lost, so it has to be done again with the dumped 
emacs.  pthread_self also allocates memory, so even if this is fixed we 
still get a loop.  I also tried using system malloc on FreeBSD 6.2, but 
that didn't work.  Emacs crashed on first realloc (heap corrupt).  I 
guess undumping on FreeBSD with system malloc is broken (or perhaps 
impossible).

There are spin locks available on BSD and GNU/Linux, see 
pthread_spin_init.  But that don't help for the pthread_self issue.  
Sigh, back to the drawing board.
