Please don't ping the reviewers. I could accept that if it is a bug fix that you might be having in your application but it doesn't seem like it is. The pull request was assigned and when the reviewer can review and merge your pull request I"m sure they will.

Good news everyone! I just checked and there is no need for a require at all (at least for ruby >= 2.0):

> ruby -e 'puts Monitor' -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-darwin12.2.0]

Monitor

@Gaurav2728 if you want, you can modify your PR to remove require 'monitor' from other files as well.

@thedarkone I think that's because rubygems happens to require it, which I guess we shouldn't rely on.

% ruby --disable-gems -e 'puts Monitor' -v
