I thought mc's lacking subshell support is a hard fact of life in Cygwin, until
the -U option was pointed out here. It's a huge improvement.

It's quite easy to kill the zombie subshells.
Put a line into /etc/crontab (assuming you're running cron):

*/6 * * * * SYSTEM ps -a | sed -n 's/I  *\([0-9][0-9]*\)  *1  *..*bash$/\1/p' |
xargs kill -KILL

This will kill all bash processes every 6 minutes, who are waiting for input in
the background (I) and whose parent process (PPID) is 1 (not a terminal, not mc).

Best regards
