Subject: implement pthread_[sg]etconcurrency.
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=ddd87b2f10baf35ed32917bd488be8bf53ad0cc3;p=musl

implement pthread_[sg]etconcurrency.

there is a resource limit of 0 bits to store the concurrency level
requested. thus any positive level exceeds a resource limit, resulting
in EAGAIN. :-)
