In general, a GUI application started in the background, like a terminal,
should detach itself from its parent process so that it survives if the
parent is terminated.
I've noticed the following sometimes surprising inconsistencies about this:
mintty
xterm &
mintty &
exit
-> all child terminals remain
mintty
xterm &
mintty &
Close/Alt-F4
-> dialog "Processes are running in session. Exit anyway?"
OK
-> xterm remains
-> mintty is killed
xterm
xterm &
mintty &
exit
-> all child terminals remain
xterm
xterm &
mintty &
Close/Quit
-> xterm remains
-> mintty is killed
cygwin console
xterm &
mintty &
exit/Alt-F4
-> console hangs
Close
-> mintty remains
-> xterm is killed
I noticed, just as a testcase, that in those cases mintty gets killed
also setup.exe gets killed.
Also, mintty can be protected from being killed by spawning it with
(mintty&)
while xterm, spawned this way from a cygwin console, still gets killed.
