Timeouts do not change when make values in dhc3conf smaller.

I can now quantify the timeouts more, I ran a simple perl script that pings
a server on the same subnet, and if it takes more than 2 seconds to reply,
it logs it.

This is the output of a 12h run. As you can see, the longer (~30 secs)
timeouts all occur exactly at 1:11 past every whole 10 minutes. Shorter
timeouts also occur, don't know what to make of that, it could be that the
system is heavily loaded around those times.
