[PATCH] Using select for remote MCJIT messages

[Renato Golin]

  I just saw a problem with my implementation.

  However, not having the counter is locking, and returning -1 on timeout is breaking.

  Furthermore, if I add the select on both children and host, the communication channel also lock.

  I think I'll have to add select on both reads and not on any write.

  I'll try again.

----------------
This is going to let pass the last cycle and let read deal with it, which is not ideal.
