 Huh, this is the first such feedback.
 Of course i use it in production environment. Also, it passes make test
suite. Could you exactly tell me what breaks and where, so that i could
reproduce the problem ? This would be very helpful.
 Actually i have some glitches with -j, but i also had glitches without this
patch.

Kind regards,
