Fix for a fairly nasty memory leak in the nsca daemon. Without this patch,
nsca was growing to ~80MB overnight under my (~1000 passive check) loads.
Unfortunately, there is still another leak in there somewhere, but it's much
much smaller now.
=46rom my testing, the leak is definately related to mcrypt; with mcrypt
disabled, there is no leak that I can see.
Patch against CVS from today is attached.
