Sadly not all servers speak CGI this days, most notably nginx, and
others often have broken CGI support.

Also CGD can act as a extremely minimal HTTP server itself to directly
host "stand-alone" CGI scripts without a 'real' web server.

The server itself uses goroutines which are very efficient, so has no
need to pre-fork, the called CGI script can't be 'preforked' because
before you fork a CGI script you have to set the relevant environment
variables for the request.

Still, forking is never the bottleneck (werc itself performs hundreds
of fork per request) and I wouldn't be surprised if CGD is not more
efficient than the CGI-handling code in most web servers, but if your
web server already supports CGI i wouldn't really bother.

Hope this answers most (all?) your questions.
