Fixes spec crashing issue (#132)

I believe this fixes #132 

@twerth I know we previously talked about in [@vc.rmq vs. rmq](https://github.com/infinitered/rmq/commit/ca07631fe6845abf8da1aca6a0b555740928422c), but in this case I think this makes sense.

 After this change I wrote this script, and there was no failures.  Prior to this change - spec failures happened at **least** 1/4 of the time.

```bash
#!/usr/bin/env ruby

50.times do
  system "bundle exec rake spec && bundle exec rake crashlog"
end
```
If there was a failure then the crash log would open (as I emptied my crash log before starting) - on master i would see a crash probably 1 out of 4 times, but with this branch, 100 times - no failure!

Thanks for helping me dig into this @vaughankg!
