If I launch a terminal emulator running an interactive command,
then type Control-Z (which would normally suspend the command),
the terminal emulator hangs. I see this with xterm, mintty, and
urxvt.
I don't see this behavior on Ubuntu, for example. There a Control-Z
is ignored.
Of course typing Control-Z isn't useful if there's no parent shell
to suspend to, but I often do so accidentally.
To reproduce, for example:
mintty less file.txt
then type Control-Z in the mintty terminal. The terminal window goes
blank, and can't be closed by clicking the "X" in the window frame.
I'm running the Cygwin X server in multiwindow mode:
XWin -engine 2 -clipboard -multiwindow -emulate3buttons
(I don't remember why I use "-engine 2". I don't *think* it's
relevant. I'll try it later without that argument and post again if
it makes a difference.)
