Got a new Emacs freeze. More info here! Read on...
Freeze just occurred:

Though, I've no process with PID 6672, as you can see on the above screenshot.
As you say, it could be the PID of Bash that already exited.

Now, killing es.exe from the Process Explorer *did unblock Emacs*, as you can
see on
http://content.screencast.com/users/fniessen/folders/Jing/media/fd8b4e53-5232-451a-9757-7623950365cd/2012-11-14_0938.png:
I just recovered where I was, in Helm, with the correct files show now -- I
had previously typed more characters in the pattern, when Emacs just froze...
Now, they reappeared, with correct results from the "locate" command.
Great news, I guess, in the understanding of what happens...

Next thing for me, then, is to try without Bash for shell-file-name:
--8<---------------cut here---------------start------------->8---
(setq shell-file-name "cmdproxy")
(setq explicit-shell-file-name "bash")
--8<---------------cut here---------------end--------------->8---
