why thrd_nomem?

I think in such a case they should just return the error code that
mtx_init would have returned. mtx_init only has thrd_sucess and
thrd_error as return codes. mtx_lock has exactly the same, mtx_trylock
adds thrd_busy to that. So the error returns of these function would
not have to be reconsidered.

I find the argument in the pthread specification about the advatages
of offering static initialization really convincing.

You are probably right. At the end this interface will probably not be
used by the people, even if we'd see some implementation, soon.

But this re-enforces the initial point of this thread (put aside the
polemics) that this interface is not yet mature. It would probably
have been better to just add a definition of "simultaneous execution"
of some sort. This then could have been the basis of the atomic
stuff.

The part on atomic types and functions (macros) is really important in
my point of view, because I am not aware of any standardization of
these operations. This is some gray zone where all compilers and
systems have some extensions.
