	That's what I had thought of, but in this case,  ps _is_ a
script itself, that runs on mawk (mulinux's very own awk
implementation). Bearing this in mind, the machine this script needs to
run on takes something like 45-50 seconds to list all current processes
(no joke), plus the grep, sed and friends, the count rises and rises and
rises... That's why I had this idea of using a little script in
/proc/somewhere directly to cut the out middle man. The thing is that I
can't quite remember where the list of processes resides (if at all, I
know that a list of all processes exists at /proc/process_id), and I
wasn't too sure of its syntax (and of the syntax needed to sed/awk it).

	Thanks,
	José
