>             Project: Thrift
>          Issue Type: Bug
>          Components: Perl - Library
>    Affects Versions: 0.10.0
>         Environment: Ubuntu 14.04 LTS, Perl 5.18
>            Reporter: James E. King, III
>            Assignee: James E. King, III
>             Fix For: 0.11.0
>
>
> The Perl ForkingServer sets SIGCHLD to be ignores so that the forks can be automatically reaped, since the ForkingServer doesn't care about the child exit code.
> The fix for THRIFT-3848 was incomplete.  It needs to reset the signal handler in the child to use a default SIGCHLD handler so any thrift handler implementation relying on SIGCHLD will execute properly.
> Also due to the fact that SIGCHLD is ignored in ForkingServer, the _collectChildren and call to waitpid() are unnecessary and can be removed, along with the children hash, from _parent().
