hm... you should know that modpnpsender was written long time ago as a
fast shot to a nice idea.
I thought no one will use that code outer a test environment. But as you
say that you are using that creepy code - let me know if there is more I
can do for you ;)
Maybe you want to check out the latest devel version, there is a new
(cleaner) module for getting performance data, not with a socket in it
but it might be faster than the normal way. It's called npcdmod.
