Yep, Arrigo looked at the TAS code for Alpha-Linux (it is commented out for
DEC Unix) and came to the conclusion that it probably only worked on specific
configurations and definitely not on multi-processor machines. He has been
trying to write the code himself, but it turns out to be extraordinarily hard
to get this working properly on Alpha (espec. multi-processor machines). I
believe he is currently trying to interest somebody in Digital in this
problem. Until a proper solution has been found, it is probably safer to just
stick to the semaphores.
