No, I understand better than you think as I do huge parallel builds every day.
The shell wrapper buffers the recipe output and then grabs a semaphore
before writing the output to it's stdout.. if another recipe has
completed and is in the process of outputting to the stdout then it
has to wait a few microseconds.
This system works reliably and has given us de-scrambled output for
the last 2 years.
