Thanks Paul!

At this point, my primary suspect is our use of recycled OVERLAPPED 
structs without reinitializing them to zero. To make matters worse, 
we're setting the OVERLAPPED's internal .Pointer field in the 
AcceptFilter 'data' case -- which we're not supposed to be doing to 
begin with [1]. We don't do that in the 'connect' filter.

This is all just theorycrafting, though. I'll try to reproduce on my end
