I think if you want to be making 8 calls per second, you should try to
limit them to bash built-ins only. One option would be to touch a
file at the beginning of the target script.
Attached is one solution that is working on my box (so far). The
whole system is noticeably less sluggish while building. `top' looks
normal again.
/tmp may not be the best place for the temp file. I suppose you could
put it in $JHALFSDIR instead.
