One caveat, from the 5.1 help information:

: Some processes, such as reclamation, will generate mount requests in
: order to complete processing. If a process has a pending mount request,
: the process may not respond to a CANCEL PROCESS command until the mount
: request has been answered or cancelled by using either the REPLY or
: CANCEL REQUEST command, or by timing out.

: Use the QUERY REQUEST command to list open requests, or query the
: activity log to determine if a given process has a pending mount
: request.

So a simple q proc (or equivalent) + canc <proc num> operation may
usually work most of the time, but may fail at certain times if you
don't also check for this, too.
