[Openmcl-devel] Process state 'Arrested' ?

The process has no "run reasons" and/or has one or more "arrest
reasons"; it isn't considered for scheduling.  (The
"EXTERNAL-PROCESS-WATCHDOG" process in 0.13.x just sort of hung around
until someone called RUN-PROGRAM; it would have made as much sense for
it to have only been created if it was actually needed ...)

When 0.13.x first starts up, :PROC says that that process is "Suspended";
after calling RUN-PROGRAM (and after the external process exits), the
process's whostate becomes "Arrested".  I'm not sure that there's really
any difference between "Suspended" and "Arrested", but I'd guess that
RUN-PROGRAM has been called at least once in the image you're running.
