   This may be an inexpensive (read 'cheap') replacement for the fuser 
fuser function . Could you try this on your machine and see what cpu cost is

   ..Logic.. ( possibly flawed)
*  'Make' must be run from the root account or via sudo so access to the 
/proc directory is not an issue.

*  We pick up the pid of the 'make' process whenever we kick start the 
timer bar but from then on we only use the 'pid' for the process status 



  # note.. DO NOT try and trace the variable makePID..
  # it changes the fuser text
makePID=$(fuser -v . 2>&1 | grep make)
makePID=$(echo $makePID | cut -d" " -f2)

write_or_exit() {

     # make has been killed or failed or run to completion, leave
   [[ ! -e /proc/$makePID ]] && echo -n "${CURSOR_ON}" && exit

     # Target build complete, leave.
   [[ -f ${TARGET} ]] && echo -n "${CURSOR_ON}" && exit

     # It is safe to write to the screen
   echo -n "$1"
