VSO_0226079_mutex is sporadically failing #1472
Description
We encountered a sporadic test failure:
Assertion failed: time_execution([this] { unique_lock<Mutex> ul(mtx, 50ms); assert(!ul.owns_lock()); }) >= 50ms,
file C:\a\1\s\tests\std\tests\VSO_0226079_mutex\test.cpp, line 327
STL/tests/std/tests/VSO_0226079_mutex/test.cpp
Lines 324 to 327 in ea156e7
It appears that system_clock behavior may be making this test unreliable.
