startup: fork before initialising the event subsystem

On FreeBSD 4.8, fork(2) doesn't actually behave like fork(2).

Namely, kqueue(2) descriptors are not inherited by the child.
IOW, we can't fork(2) after we get the kqueue(2) descriptor.

So we'll just have to rely on people to actually read the
server log file if they want to understand why their server
is dying during startup.
