*	Disable single thread optimization for open_memstream	Szabolcs Nagy	2017-07-14	1	-0/+101
	Single thread optimization is valid if at thread creation time the optimization can be disabled. This is in principle true for all stream objects that user code can access (and thus needs locking), using the same internal list as fflush(0) uses. However in glibc open_memstream is not on that list (BZ 21735) so the optimization has to be disabled. * libio/memstream.c (__open_memstream): Set _IO_FLAGS2_NEED_LOCK. * libio/wmemstream.c (open_wmemstream): Likewise. * nptl/tst-memstream.c: New.
