Hi, Hans-Peter,
That quirk where you quad-fx edif2 twice...
When edif2 starts, it fork()s a process to watch for changes in the
working-file copies of the functions passed to emacs, and it also opens
a POSIX message queue so the monitor process can communicate changes to
APL. When you quad-fx-ed edif2 twice, all that was duplicated--two
monitor processes, another sender on the queue, and more signals being
emitted. I've put a patch in (but haven't committed it yet, and it
should fix the segfault) that prevents all that, but my question is
whether the "session blocked" bug happens only after the second
quad-fx. I just can't reproduce the blocking bug here, so I'm looking
desperately for some non-obvious cause.
Thanks,
Chris

Hello Chris,
I have just one process running.
I recompiled and reinstalled edif to make sure it's the most recent
version.
During editing with emacs:
session is blocked, then in APL session
Ctrl C
fg
'some data' ENTER - no response
in emacs: save
in APL session:
'some data' replayed
'some data' response

There is on other quirk too:

Is there any chance you have multiple APL processes running
concurrently? Apparently, that causes problems I hadn't caught before.

Hello Chris,
edif2 blocks the apl session again.
edif: latest git.
apl: 1069M

Not that I expected otherwise, but edif and edif2 still work as
expected.

I just committed a minor patch to edif, fixing a relatively low
probability bug involving a possible message queue name
collision if you have two or more APL sessions open simultaneously.
