The --pidfilepath asks for an absolute path as an argument. This is required because the server does a chdir() to root before we write the pidfile and that write will fail if you just specify a filename (e.g. -pidfilepath proc.pid).

This is inconsistent with --logpath which does accept a non-absolute path.

The server should either report an error for a non-absolute path or prepend the cwd() to the pidfilepath argument for non absolute arguments.

This happens when the --fork argument is used.
