apache2-mpm-perchild 2.0.55-4ubuntu2.2 (i386 binary) in ubuntu dapper

 Perchild is the grown up, mac daddy version of suexec for apache2. Rather than
 execute a cgi script as a given user, perchild forks a process for each vhost,
 then su's to the correct user/group for that vhost.
 .
 Each process then uses a thread model similar to that of the worker mpm.
 .
 THIS MPM IS NOT CURRENTLY EXPECTED TO WORK CORRECTLY, IF AT ALL. IT IS UNDER
 VERY HEAVY DEVELOPMENT.
 This mpm is still highly experimental, and should be used with care.
