`SRWLOCK`, as used by `std::shared_mutex`, is a inherently unfair mutex
and makes no guarantee whatsoever whether a thread may acquire the lock
in a timely manner. This is problematic for our renderer which relies on
being able to acquire the lock in a timely and predictable manner.
Drawing stalls of up to one minute have been observed in tests.
This issue can be solved with a primitive ticket lock, which is 10x
slower than a `SRWLOCK` but still sufficiently fast for our use case
(10M locks per second per thread). It's likely that any non-trivial lock
duration will diminish the difference to "negligible".
