1: Wakes are orderless
2: uWordSize must be less than or equal to 8 bytes
3: only the least significant 32bits are guaranteed to be used as wake signals
in either mode:
1: WaitOnAddress[...] can wake at any-time if a fast path permits.
(we only care about strict guarantees during the deep slow-path yield operation.
after the first pass, after a cache miss, after a fast path succeeds,
it's anybodys guess who will *return* first. on the other hand, a set of 5 threads
already in the kernel *should* wake in the expected order. otherwise, WaitOnAddress[...]
just assumes pTargetAddress != pCompareAddress is an orderless return condition.)
* By default: UNIXes and targets below/inc Windows 7 will be in userland emulation mode for performance reasons.
* Linux and other targets can directly interface with their futex interface under a smaller wrapper;
