In fact the sh process could have come from something else. Bug 703472
or upstream bug https://bugzilla.mozilla.org/show_bug.cgi?id=705543 is
actually a more general bug.

When I did the same thing a second time, I got no problems. But if
https://bugzilla.mozilla.org/show_bug.cgi?id=705543 is the cause,
it is not always reproducible. And with the particular case where
some pane (proposed list of search results, menu...) is open, it
is known to grab the focus (but Fvwm key sequences still work) and
mouse clicks while it is open. A combination of both conditions is
even more difficult to reproduce (I'll try if I have some time).

Concerning the problem with the virtual terminal, I was wondering
whether the switch worked, but the display didn't follow (in which
case it could explain why there was no longer any apparent reaction
to key presses -- I didn't try Alt-F7 to confirm); I had a similar
problem in the past, but it was different since the display remained
frozen also during shutdown. Here, when I killed the fvwm2 process
via SSH from my phone, I got the gdm3 login again, without needing
to do anything else.

They are probably unrelated.
