On Windows, this changes the EventContext::wait() return type from Vec
to SmallVec; this removes an extra conversion step, since the only
caller, WaitContext::wait(), constructed a SmallVec from the return
value anyway.
On Linux, this lets us get rid of the PollEventsOwned structure, since
the SmallVec contains the events and does not need to point back at a
separate type for storage.

Switch the uses of std::sync::Mutex to our custom sync::Mutex, which
panics internally if lock() fails. This helps to reduce the instances of
