but again, it's a semantic change.

the old system was a constant identifier that never changed over
the life of the process (it may not be unique.)  the argument list
is under the control of the process itself, so what's being matched
here is a different thing.

i guess i've known about the 16-byte limitation and understood it,
but since it was p_comm it was a reasonable limit.  now there is
no way to match against p_comm at all, right?
