Fix bug #5464. Pointed out by Herb @ Connectathon. In fork_domain_child() we call :
CatchChild();
*before* we fork the domain child. This call establishes a signal handler that
eats SIGCLD signals and doesn't call sys_select_signal() as the main daemon
SIGCLD handler should do. This causes the parent to ignore dead children and
time out, instead of calling winbind_child_died() on receipt of the signal. The
correct fix is to move the CatchChild call into the child code after the fork.
Jeremy.
