OK, I guess it's just that machine, I don't know why.  I tried it on
my other Pi with Raspbian Buster and that doesn't do it.  Nor a couple
of Debian machines running Buster and Spike.  I should have tried that
before posting.  I hadn't really kept track of where it was happening.
That's my summer Pi so I've been spending a lot of time on it lately
and imagined the problem was everywhere.

Right, sounds like the launcher scripts and/or rxvt code has changed in 
this regard, we never did anything to child processes on the mc side - so 
what Alan describes is actually the normal vanilla behavior.

I tested mc-4.8.25 with following terminal emulators:
mate-terminal-1.12.1
xterm-320
urxvt-9.20

All of them works as described above: child window is alive after parent
one closed.

Hi Alan,

only an idea for workaround: use "nohup" so your rxvt should be really 
independent...

(man nohup)

Subprocess strangeness

2020-09-13 Thread Alan Corey via mc
I've been using mc for 20 years or more and only seen this in the last
couple weeks.  I use rxvt as my terminal emulator mostly.  I could
navigate to where I wanted another terminal in mc, then type rxvt &
and a new independent window would open there.  I could close the
original window and the new one stayed open.

Now whenever I close the parent one all the children close too, even
though I remember the & to make it independent.  At first I wasn't
sure it was happening.  I just did this: type mc in an rxvt, type rxvt
& in the new one, hit F10 in the original and the new one closes.  The
new one somehow depends on mc still running, lxterminal works the same
way.

This is mc 4.8.22 in Rasbian Buster, I mostly only install it from the
debs.  Some routine apt-get update and upgrade did this.
