 I get instant hangs. Usually there is no CPU usage at all. If I try to
 attach gdb to a firefox-bin process, it barfs.
 
 One time I got a hang at startup with 100% CPU usage.
 
 It was possible to to a ktrace on it. But the ktrace.out is 50 MB, so I
 won't post it here. :-) I can mail it if anybody is interested.
 
 One thing that struck me when going over the tracedump was this:
 
  23905 firefox-bin CALL  kse_thr_interrupt(0,0x6,0x7fffffffd120)
  23905 firefox-bin RET   kse_thr_interrupt -1 errno 22 Invalid argument
 
 It happens on all the firefox-bin processes. It looks like is being
 called with a NULL pointer as its first argument. This looks fishy to
 me. If it is suspect, the trouble might be in the pthread library?
 
 BTW, the prototype for kse_thr_interrupt in the kse(2) manpage doesn't
 match /usr/include/sys/kse.h
