the bug 6399 and 14300 make a good case for providing a gettid() API. As
developer of high performance trace tools the lack of a gettid() is odd
give that TID values readily available from the TCB.

So I agree that it should not have be a PPC specific API and it is not a
POSIX API, but GLIBC provides other non-POSIX API and I don't understnad
why it would be hard to convince the community to add such simple and
obviously useful API.
