Well, I wasn't satisfied so I played with it some more. The user
script is "cm". It will take the arguments start, stop and check.  
"Start" will start the mail-check utility in the background, "Stop"  
will kill the background job, and "Check" will take a look, then quit.  
Note that you can do a quick check even while it is already running in
the background. The is handy if you think you might have missed a
notification.

"cm" calls cm.scr to do the actual work.

 cm.scr check

if [ "$COMMAND" = "start" ]; then
 if [ -f $HOME/.cmpid ]; then
  echo "`basename $0` is already running."
  exit 1

 cm.scr start &
 exit

if [ "$COMMAND" = "stop" ]; then
 if ! [ -f $HOME/.cmpid ]; then
  echo "`basename $0` is not running."
  exit 1

 kill `cat $HOME/.cmpid`

You're right ... I need a life. :-)
