Log:
�Introduce a non-portable function pthread_getthreadid_np(3) to

note its introduction.
Stupid question: how is this different from pthread_self() ?
Isn't the pthread_t value returned unique across the system, or is
it relative to the process somehow?
pthread_self(3) returns an opaque type pthread_t, e.g.,
pthread_equal(3) must be used to compare two thread IDs.
pthread_getthreadid_np(3) returns an integral type int, which is
actually td_tid of the calling thread for libthr(3).
Please see the following discussion:

Yes, we understand that Linux has it, and IBM has made
some sort of compat functions for accomplishing the same,
but why are developers so lazy that they cannot use
pthread_equal() instead of "="? Or use something like
pthread_[gs]etspecific()?
Yes, this is a rhetorical question. Since Linux has it,
we must also :-(
