Number of Nagios Processes Distributed Monitoring

Here is a "stupid" diff against stock 1.0 (although it should apply to 1.1 as
well).  I say stupid because it a) doesn't fix the real problem (the write 
blocking forever is caused by something?) and b) isn't really freindly about 
how it "fixes" the problem (the stuck process is terminated with prejudice).  
It has however kept my machine from crashing from running out of memory 
(had I been running fbsd, sigh) for a couple weeks now, which is worth the 
downsides IMHO.  I didn't bitch about it because it looks like 2.0 is doing 
some different stuff in the process handling, so it seemed a little premature 
to complain about that there.
