Oh, I'm sorry, I was thinking about the Linux-Alpha code, for which
there has been an inline-assembly version of tas() for a long time;
and it was that code that we asked the DEC people about.  I had
forgotten that the OSF port uses a different semaphore method.

Is there a reason we couldn't use the Linux-Alpha code on OSF too?
I'd just as soon minimize the difference between the two ports ...
