 Replying to [comment:2 evanmiller]:
 > When I was tinkering with Ruby on PPC, I ran into some issues with
 coroutines. It's possible that's the source of the hangs, but it could be
 something else. Try attaching to the hanging process using Sampler (found
 in Developer > Applications > Performance Tools). If you record a sample
 then you should be able to see where the process CPU time is going and
 maybe get a hint about what's freezing.

 I have done it, but in what way I should export its output?

 Besides, a basic sampling via Activity Monitor gives this:
