boost/thread/win32/basic_timed_mutex.hpp: Ignores failures from WaitForSingleObject

Description (last modified by viboes)

boost/thread/win32/basic_timed_mutex.hpp ignores failures from WaitForSingleObject?. There's not much point in looping if its just going to fail again:

    unsigned const retval(win32::WaitForSingleObject(sem, ::boost::detail::win32::infinite));
    BOOST_VERIFY(0 == retval || ::boost::detail::win32::wait_abandoned == retval);

The use of BOOST_VERIFY is good, but I'm not sure about the WAIT_ABANDONED. WAIT_ABANDONED usually indicates a bigger problem, and continuing might not be a good idea.

See #8422 to understand when WAIT_ABANDONED was added. Reopen #8422 if you don't agree with the resolution.
