 I have tried out the supplied patch and it works for me on -current with
 free -> xfree. There is another problem: I see a lot of calls into
 libpthread before it is initialized, and those calls are made from within
 libc.
 
 I think that the setup for libpthread should happen via a constructor in
 libc, which solves the problem for me. Below is the libc bit; in libpthread
 we just override __libc_thr_init().
 
 Thanks,
 Andrew
