no, not for mtx_init. in n1570 it only has thrd_error as an error
indication.

yes. In practice, on hosted environments running out of memory during
initialization is probably nothing that is heard of much.

I don't think that just one proprietary implementation will contribute
to a wide spread acceptance. You'd need at least one major compiler
implementor adopt it on each side, windows and unix. On the unix side
this'd better be gcc or clang, so something with an open license of
some sort.
