FCGI::ProcManager is used to serve as a FastCGI process manager. By
re-implementing it in perl, developers can more finely tune performance in
their web applications, and can take advantage of copy-on-write semantics
prevalent in UNIX kernel process management. The process manager should be
invoked before the caller's request loop.
