A non-consuming permit looks quite like a Win32 event object yes, 
except it has stronger guarantees useful for many-waiter 
many-signaller situations. A permit is completely user space though, 
and portable.

A consuming permit looks totally different to Win32 event objects. I 
am not sure what else it resembles actually, perhaps a reusable 
future/promise.
