Actually, there may be a nice way to allow --pid=PID to
integrate seamlessly with inotify support.

I think you can add an IN_DELETE_SELF inotify watch on the "/proc/PID"
directory.  I suspect that every system with inotify support also
has usable /proc/PID directories.  The only requirement seems to be
that the desired directory be readable.
