// Theory of operation for waitForConditionOrInterruptNoAssertUntil and markKilled:
//
// An operation indicates to potential killers that it is waiting on a condition variable by setting
// _waitMutex and _waitCV, while holding the lock on its parent Client. It then unlocks its Client,
// unblocking any killers, which are required to have locked the Client before calling markKilled.
//
// When _waitMutex and _waitCV are set, killers must lock _waitMutex before setting the _killCode,
// and must signal _waitCV before releasing _waitMutex. Unfortunately, they must lock _waitMutex
// without holding a lock on Client to avoid a deadlock with callers of
// waitForConditionOrInterruptNoAssertUntil(). So, in the event that _waitMutex is set, the killer
// increments _numKillers, drops the Client lock, acquires _waitMutex and then re-acquires the
// Client lock. We know that the Client, its OperationContext and _waitMutex will remain valid
// during this period because the caller of waitForConditionOrInterruptNoAssertUntil will not return
// while _numKillers > 0 and will not return until it has itself reacquired _waitMutex. Instead,
// that caller will keep waiting on _waitCV until _numKillers drops to 0.
//
// In essence, when _waitMutex is set, _killCode is guarded by _waitMutex and _waitCV, but when
// _waitMutex is not set, it is guarded by the Client spinlock. Changing _waitMutex is itself
// guarded by the Client spinlock and _numKillers.
