I understand your concern for sure ;-) Maybe that's the very thing you're thinking about but ... AFAIK a spinlock is the usual paradigm in scenarios where one doesn't anticipate contention but needs to be aware of it 'just in case'. With InterlockedCompareExchange() and Sleep() it should be quite simple to create one that's very efficient in the usual scenario.
