ENOSPC: System limit for number of file watchers reached

[bes-internal]

Ungit trying watch all files in subdirs, ignore .gitignore, and dies. But should only watch to tracked files(git ls-files).

Agreed, this is quite annoying. This prevents me from using ungit when working on either Node.JS or Rust projects.

This is indeed annoying... I've stopped working on ungit but you can get around via doing ulimit -n 1655350 for now.

If I remember correctly file watcher is set to not watch ignored files
