Time to rock the IPC?

#!/bin/bash
MAGIC=5

system_time_epoch() { date +%s; }
file_time_mod() { stat --printf='%Y' $1 ; }
file_age() { echo $(( $(system_time_epoch) - $(file_time_mod "$1") )); }

tmp="/tmp/michael_jackson_touched_my_$$"
touch $tmp

(
while test $( file_age $tmp) -lt $MAGIC; do sleep 1; done
xmessage "wtf? you let him touch your $$"
) &

while ! ssh $there ; do
        touch $tmp
done
