Transgaming relies on a property of the pipe code and old scheduler. I
actually have a fair bit of sympathy for them doing this. Its not like they
broke rules they tested scenarios and picked one that was fastest at the
time.

As far as I can tell the stuff they really really need is futex locks, which
are in our 2.4 now (but not base 2.4) and are in base 2.6.
