# rwhocache, which is a bash script, seems to trigger a bug in certain
# versions of bash (some kind of memory leak which ultimately causes
# it to crash).
#
# This script periodically checks if rwhocache is still running and
# restarts it if necessary.  You may want to start it from the
# boot-time startup script for rwhod++.
