I was having some problems querying mongo on synchrony. The gemspec seems to be outdated.
The problem was: "undefined method `find' for #<EventMachine::Mongo::Connection
Now works like a charm. All tests passing too.
Update em-synchrony on gemspec.
Update em-mongo on gemspec.
Merge pull request #82 from endel/master
Update em-synchrony and em-mongo on gemspec.
