A related issue is that when you close any of the pty-based terminals
with mc started from bash running in it, the mc process doesn't get
killed. Bash does of course forward the SIGHUP it gets from the
terminal to its child processes, and manually sending SIGHUP to the
orphaned mc does get rid of it.

A similar issue was previously reported against the joe and mined
editors at http://cygwin.com/ml/cygwin/2010-04/msg01013.html. This
still needs a simple test case though.
