 This problem should be fixed for 6.2-STABLE by
 usr.sbin/rpc.statd/statd.c 1.12.8.2 (Sun Aug 12 01:46:19 2007 UTC) and
 for 7.0-CURRENT by statd.c 1.15 (Sun Aug 5 16:33:06 2007 UTC).
 
 The warn() call should probably be changed to err() because the
 implemention does not have code to handle the case where mmap() fails.
