We were closing file descriptors in the child processes for security
reasons. Alas, the APC MasterSwitch kept an open socket which needed to
be handed from the parent to the child process which we were also
closing...

Luckily, it's a UDP socket and not TCP, or else it would be even worse
;-)

But, so simply not closing it is sufficient.
