Oh dear.
Still, the shell backend seems to work anyway.
The Solaris fork() manpage says:
     If a Solaris threads application calls fork1()  or  a  POSIX
     threads  application  calls  fork(), and the child does more
     than simply call exec(), there is a possibility of  deadlock
     occurring   in   the  child.
OSF Alpha says something similar:
     the child process should only execute operations it knows will
     not cause deadlock until one of the exec functions is called.
I can't find anything about threads vs. fork() in the Linux manpage.
