relayd - prefork option seems to be ignored

[Tobias Feldhaus]

According to relayd.conf(5) the prefork option should spawn the defined
number of processes to handle relayed connections - the default is 3.

I've tried setting it to 5, 10, and 12 on OpenBSD 5.8 - but it seems
like it is getting ignored, as ps(1) always shows me 3 relay processes,
which is the default number:

USER     PID    COMMAND
root     17010  relayd: parent (relayd)
_relayd   3243  relayd: pfe (relayd)
_relayd  16594  relayd: hce (relayd)
_relayd   4279  relayd: ca (relayd)
_relayd  28332  relayd: ca (relayd)
_relayd   4436  relayd: ca (relayd)
_relayd  24605  relayd: relay (relayd)
_relayd  19110  relayd: relay (relayd)
_relayd  15295  relayd: relay (relayd)

Am I missing something?
