This issue doesn't show up on Windows or Linux. I can't test on Mac.
Can anyone of you running ooRexx on Mac confirm it? Does it happen for you
too?
We don't have too many fork()'s in our Code - for this issue probably only
those in APIService and SysLocalAPIManager might be relevant. Would anyone
be willing to add printf's after each fork, giving the returned pid, and
build and run it. Rony, maybe?
This might pinpoint which of the forks is the culprit.
Thanks!!

In answer to your questions:
* `oorexx` is a symlink to `rexx` in the installation target.
* Yes, the process seems to linger indefinitely.
* Yes, processes accumulate over time. (I first spotted the problem when I
had 50+ sleeping processes, all associated with the same script.)
Finally, here's the result of your test, run a few times:
~~~
$ for i in {1..5}; do oorexx -e "say SysQueryProcess('pid')"; done
31022
31024
31026
31028
31030
$ ps ax | grep rexx | grep -v grep
31023 ?? Ss 0:00.00 oorexx -e say SysQueryProcess('pid')
31025 ?? Ss 0:00.00 oorexx -e say SysQueryProcess('pid')
31027 ?? Ss 0:00.00 oorexx -e say SysQueryProcess('pid')
31029 ?? Ss 0:00.00 oorexx -e say SysQueryProcess('pid')
31031 ?? Ss 0:00.00 oorexx -e say SysQueryProcess('pid')
~~~
(Note that I killed 16195 just before running this.)

ooRexx doesn't exit cleanly on macOS, leaving behind a sleeping process:
~~~
$ ps ax | grep oorexx | grep -v grep
$ oorexx -e 'say 123'
123
$ ps ax | grep oorexx | grep -v grep
16195 ?? Ss 0:00.00 oorexx -e say 123
$ oorexx -v

N.B. I'm unable to reproduce the problem on Linux.
