jung command fails on large directories on Mac OS X

[fardog]

This was tested on Mac OS X "Mavericks" on an rMBP (15-inch Early 2013).

Seemingly when working with large directories, jung will fail. I'm assuming it's large directories, because it will work fine with a directory with one or two files in it, but for my actual use-case, it fails. To replicate, perform the following:

npm install -g sails
sails new testproject --linker
cd testproject
npm install
jung -- cat package.json

This will fail with the following:

fs.js:1051
    throw errnoException(process._errno, 'watch');
          ^
Error: watch EMFILE

Unfortunately, it is due to a system-level limit on the number of file event watchers that can be registered, so the solution is not immediately obvious. Until I can fix it, if you don't need to watch a directory it's best to exclude it with the --notdirs, -D flag to avoid these kind of issues.

For example, jung -D node_modules -- cat package.json

ok, that works fine. i'll leave it to you if you want to close this issue, but it's resolved for me.
