Sure, running the general merge-sort utility sure slows it down.
But 'who|wc -l' is so close in performance on this (relatively puny)
system that it would take a practically infinite number of invocations
before it would repay the resources that would have to be spent to
install the special-purpose who -q hack.  That, after all, was the
point of the comments against such hacks.
