2340	"100% CPU and growing memory usage when enters directory ""foo [bar]"", hangs when exits"	livibetter		"If there is a directory name with square brackets, e.g. `foo [bar]`

mc will consume entire CPU and continuously use more and more memory if enter such directory. In `htop`, it looks like

{{{
/usr/bin/mc -X
 `- bash -rcfile .bashrc
   `- bash -rcfile .bashrc
}}}

The last one process is the one consumes CPU and memory. Normally, it should have one `bash`. Somehow, it is spawned when enter that directory.

If exits the directory to upper directory, mc will hang.

Killing that bash can resolve the hangup.

If run `mc --nosubshell`, the problem won't show.
