Switching away from Brackets project is very slow on Mac

[njx]

This seems to have been introduced by e60e513.

1. Clear cache
2. Open the Brackets project
3. Open a JS file in the project
4. Using the recent projects dropdown, switch back to the Getting Started project

Result: Long pause, on the order of 10-15 seconds, before the other project opens. This pause also happens if you quit or reload Brackets.

This doesn't seem to happen on Win. @peterflynn is looking into it.

Marking high priority for sprint 37

(Actually, @SAplayer noticed this on Win 8.1 as well, so it might not be Mac only.)

It seems to depend on the order of for..in, so it could vary quite unpredictably on different systems.

This is FBNC now, right? I'll try to pull it (if github is working :)) and test it.

Seems to be working great. It also fixes a problem I was seeing yesterday, where if I had the BracketsExtensionGrabber folder open, and was running the grabber at the same time (which downloads into that folder), Brackets would freeze a lot, presumably for similar reasons. Now it doesn't cause a problem at all.

Closing.
