Not quite - that's prefork :-)
Forkserver forks on every connection, but has the perl code pre-parsed in
memory which is a lot of the overhead when using tcpserver.
There's probably also a significant memory footprint difference between n
copies forked from a single ancestor versus n copies each execed
independently.
