The spawned children are attempting to write to the rw FIFO.  Since the FIFO
queue gets full (it's not very large, maybe 8K max), they block until the
reaper reads from the FIFO, and thereby emptying the queue.  That's all the
children are doing, AFAIK.

I'm not sure that having many nagios children is bad, though; it's not like
they are doing much.
