+# rump_server_check_memleaks detects memory leaks.  It can detect leaks of pool
+# objects that are guaranteed to be all deallocated at this point, i.e., all
+# created interfaces are destroyed.  Currently only llentpl satisfies this
+# constraint.  This mechanism can't be applied to objects allocated through
+# pool_cache(9) because it doesn't track released objects explicitly.
