Are you running grep with `shell-command` (M-!)? Using M-x grep, `async-shell-command` (M-&), and invoking grep directly in shell, eshell, term and ansi-term all leave emacs as responsive as normal for me. shell-command is the only one that seems to hang.

I'll also add ivy[1] and helm[2] as alternatives to Ido which are very popular completion systems with integrations that span the package ecosystem.

Thanks! I did not know about async-shell-command!
