Starts the FastCGI server. If C<$listen> is set, then it specifies a
location to listen for FastCGI requests;
- Form Meaning
- /path listen via Unix sockets on /path
- :port listen via TCP on port on all interfaces
- hostname:port listen via TCP on port bound to hostname

Options may also be specified;
- Option Meaning
- leave_umask Set to 1 to disable setting umask to 0
- for socket open
- nointr Do not allow the listener to be
- interrupted by Ctrl+C
- nproc Specify a number of processes for
- FCGI::ProcManager
- pidfile Specify a filename for the pid file
- manager Specify a FCGI::ProcManager sub-class
- detach Detach from console
