Like hell I wrote that!  AT&T created PCATCH to allow a module that sleeps
*ABOVE* PZERO to be notified when it gets interrupted out of the "sleep", so
that it can clean things up.  It was not created "to allow interrupting sleeps
below PZERO"; in fact, it *DOESN'T* "allow interrupting sleeps below PZERO".
