Jason Gedge 7304d06c0b Use threads to avoid blocking reads/writes in externals. (#1440) ... In particular, one thing that we can't (properly) do before this commit is consuming an infinite input stream. For example: ``` yes | grep y | head -n10 ``` will give 10 "y"s in most shells, but blocks indefinitely in nu. This PR resolves that by doing blocking I/O in threads, and reducing the `await` calls we currently have in our pipeline code.		2020-03-02 06:19:09 +13:00
