Comment (by elixyre):

 I pushed the modifications done with Florent about mac os problem.

 It seems there still exists the problem of synchronization with the `Pipe`
 (of the worker) but... it is never appear... so may be I am wrong.

 Is it possible that two distinct process write in the same time on the
 `_write_task` of a worker?
