Which could be the reason for the problem, btw, because Cygwin console
programs work differently wrt their standard streams than native
Windows programs.

This is normal: I guess es.exe exits when it's done doing whatever it
was that helm-for-files invokes it.

> In fact, Emacs launches a bash which launches a es.exe process.

If helm-for-files uses shell-command or its ilk to invoke es.exe, then
this is normal.

The question is, what do you see in Emacs subprocesses when Emacs
hangs.
