Yes, as discussed in http://www.allegro.com/papers/whorun.html,
that "(..)" means (usually) that it is a process that was started by
someone pointing to a procedure in NL.PUB.SYS (or SL.PUB.SYS) and
saying "start!".

As (above) discusses, the stack trace shows that the procedure in
question is io_mgr_process.  Thus PIN #17 is a process that was started
by someone (privileged) pointing to io_mgr_process in NL.PUB.SYS and
saying "start!".  Now, as to what io_mgr_process is....it appears to be
a helper process for I/O messages (like a port_facility process), but
beyond that I'm not sure.

Yes..thats all the Measurement Interface gives you, apparently.
Luckily, :), SHOT doesn't use the MI...
 
SHOT shows:
