+# CHILD PROCESS MEMORY OPTION
+# This option determines whether or not Nagios will free memory in
+# child processes (processed used to execute system commands and host/

+# CHILD PROCESS FORKING BEHAVIOR
+# This option determines how Nagios will fork child processes
+# (used to execute system commands and host/service checks).  Normally
+# child processes are fork()ed twice, which provides a very high level
+# of isolation from problems.  Fork()ing once is probably enough and will
+# save a great deal on CPU usage (in large installs), so you might
+# want to consider using this.  If you specify a value here, it will
