Atom unresponsive while performing "Find in Project"

[scouten]

Repro Steps

1. Open Atom with a project that has many files in it. For example, in my test projects:

$ du -sm
270 .
$ find . -type f | wc -l
   32967

1. Perform Find in Project in this project. I don't believe it matters what string you use.
2. While Atom is finding in this project, click on another tab in the main window.

Expected: Tab opens immediately.
Actual: Tab opens after a delay of several seconds.
