[mp2.0] Apache::SubProcess deFUNct sub-process

-------------8<---------- Start Bug Report ------------8<----------

1. Problem Description:

  Apache::SubProcess does not appear to be 'fully' working.

  When calling:

        Apache::SubProcess::spawn_proc_prog($r,'/tmp/proc.pl');

        Process tree looks like:

root      3239   /usr/local/apache2/bin/httpd
apache    3242    \_ /usr/local/apache2/bin/httpd
apache    3243    \_ /usr/local/apache2/bin/httpd
apache    3343    |   \_ [proc.pl <defunct>]
apache    3244    \_ /usr/local/apache2/bin/httpd

        - proc.pl is owned by 'apache' and is executable.
                - simply creates a file '/tmp/ran.apache'.

        - 'ran.apache' file never gets created.

2. Used Components and their Configuration:

  MP_AP_PREFIX   => /usr/local/apache2
  MP_GENERATE_XS => 1

3.  Plea for sanity

  This is the last compatibility hurdle for my apache/perl 1.0->2.0 project.

  For the life of me, I just can't see what the problem is.

  If more information is needed, don't hesitate to ask.

  Any help would be greatly appreciated.
