High latencies problem.

[D. Emmanuel Feinsmith]

I have implemented an open source Nagios Event Broker which is a multi- 
threaded Event Broker written in C which replaces NSCA and inserts the  
service/host check results directly into the internal nagios check  
result queue, completely bypassing the command pipe and the command  
pipe reader thread. It also allows you to do remote command execution  
and a bunch of other things.
