What steps will reproduce the problem?
1. Install 2.3.6
2. git clone --depth 1 git://github.com/mozilla/pdf.js.git pdfjs
3. cd pdfjs
4. time( node make lint)

I expect it to finish in less than a minute, instead it takes over 6 minutes 
and sometimes dies.

Please provide any additional information below.
On version 2.3.5 the command took 36 seconds.

Or if you don't have node you can just run:
gjslint --nojsdoc src/*.js web/*.js test/*.js test/unit/*.js 
extensions/firefox/*.js extensions/firefox/components/*.js 
extensions/chrome/*.js

2.3.6 defaults to using multiprocessing. This has caused issues in Windows, and 
I wonder if in some backwards way it is hurting performance on OSX. If you run 
gjslint with the flag --nomultiprocess does it still take as long?

Running with above flag did not help, it still hasn't finished and it's been 
over 5 minutes.

 time(gjslint --nojsdoc --nomultiprocess src/*.js web/*.js test/*.js test/unit/*.js extensions/firefox/*.js extensions/firefox/components/*.js extensions/chrome/*.js)
