Of couse, I prefer a fix too, but as you can see our testbed's coverage
isn't good enough to find race conditions.
I can provide you SSH access to a box to recreate, test and fix that
issue if you like.

I hope we can focus on a fix instead a revert, this concept is quite critical
if we ever want to move Maven forward. There's actually a second branch waiting
to be merged to solve the reverse order of modules when using build/consumer.
I'll try to have a look this weekend, and of course any help here is
appreciated.
thanks,
Robert

The "pipe not connected" happens in more than 50% of all cases.
When running Core ITs some ITs just hang forever.
From googling, this is a race condition in the code.
