Summary:                    [patch] Asterisk produces many zombie processes
while under load.
Description: 
Once under a non-trivial load (trivial being the 6 phones in our office
that we've been testing with for the past week, non-trivial being around a
hundred sip clients and about 7 or 8 simultaneous DAHDI calls), Asterisk
starts producing a high volume of zombie processes - say a few hundred a
minute. If left alone, this crashes the operating system within a few
hours, but not before calls start getting very flaky.

    Kill zombies.
    
    When we ast_safe_fork() with a non-zero argument, we're expected to
reap our
    own zombies.  On a zero argument, however, the zombies are only reaped
when
    there aren't any non-zero forked children alive.  At other times, we
    accumulate zombies.  This code is forward ported from res_agi in 1.4,
so that
    forked children are always reaped, thus preventing an accumulation of
zombie
    processes.
