Windows NT synchronization primitives for Linux

I am actually more familiar with Windows events than futexes so excuse my heresy :) One problem I see is auto-reset events, where pulse specifically only wakes one *and only one* of the waiting threads. But I don't think futexes don't have an easy way of guaranteeing the wakes happen atomically in that fashion: it seems like this would wake *at least* one waiting thread, absent a very clever workaround or modifying the kernel directly. Of course I could be missing something. But I suspect Windows kernel being written to atomically wake up a single waiting thread is probably expensive to emulate on Linux.
