mailutils: pop3d(SIGCHLD)

[Alain Magloire]

Bonjour

    4. pop3_sigchld() lacks signal() call, due to which the signal handler
    gets cleared after first SIGCHLD and all subsequent children, when
    finished, just hang around like zombies.

Right, good catch.  I took the approach of using sigaction() if it is
available.  The sigaction() semantics are well defined and signal does
not need to be rearm.  Fall back to what you propose if sigaction()
is not available.

Thanks
