Subject: [PATCH/WIP v2 08/14] read-cache: add GIT_TEST_FORCE_WATCHER for testing

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Fri, 17 Jan 2014 16:47:34 +0700

This can be used to force watcher on when running the test
suite.

git-file-watcher processes are not automatically cleaned up after each
test. So after running the test suite you'll be left with plenty
git-file-watcher processes that should all end after about a minute.
