/**
 * The RtlWaitOnAddress routine waits for the value at the specified address to change.
 *
 * \param Address The address on which to wait.
 * \param CompareAddress A pointer to the location of the previously observed value at Address.
 * \param AddressSize The size of the value, in bytes. This parameter can be 1, 2, 4, or 8.
 * \param Timeout The number of milliseconds to wait before the operation times out. If this parameter is NULL (INFINITE), the thread waits indefinitely.
 * \remarks WaitOnAddress is guaranteed to return when the address is signaled, but it is also allowed to return for other reasons.
 * For this reason, the caller should compare the new value with the original undesired value to confirm that the value has actually changed.
