Hi, Jeremy:
     There is still bug in winbindd_reinit_after_fork(), when
TALLOC_FREE(domain->check_online_event), the destructor is called, which
refers to null pointer, because te->event_ctx is set to NULL in
event_context_destructor(), which is called by reinit_after_fork(). So,
te->event_ctx->timer_events in timed_event_destructor() crashes the process.

Patches are in attachment for v3-0-test and v3-2-test, please review them.

After the fix applied, everything works for me very well. :-)

11th, Jan
