I don't quite understand how WAMP fits into this.  WAMP is Windows only,
and on Windows `PHP_CLI_SERVER_WORKERS` is not supported.

Besides that setting an environment globally is not necessarily
possible, this looks somewhat backwards to me, and is in my opinon way
too special =E2=80=93 why would only the built-in development server adver=
tize
itself as a development environment?
