------------------------------------------

             Summary: Document Perl ForkingServer signal restriction imposed by THRIFT-3848 and remove unnecessary code
                 Key: THRIFT-4065
                 URL: https://issues.apache.org/jira/browse/THRIFT-4065
             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


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.

This means any perl handler is not allowed to implement its own SIGCHLD handler.  This limitation is not documented in the perl readme, but it should be.

In addition, the fix for THRIFT-3848 was incomplete.  Due to the fact that SIGCHLD is ignored, the _collectChildren and call to waitpid() are unnecessary and can be removed, along with the children hash, from _parent().
