note that we've been seeing hard-to-reproduce problems along these
lines in the debian packages.  debian bugs:

#338391: nagios-common: nagios often leaves multiple processes around 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=338391

#376070: nagios-common: init script sporadically fails to see existing nagios process 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=376070


comments would be welcome.
