The issue is when a file lock is acquired immediately it is leaving an 
OVERLAPPED structure in the pending I/O cache. That OVERLAPPED structure 
is recycled via the I/O completion notification but it's possible that a 
close gets in around this time and attempts to clean up. If it grabs it 
before the thread handling the I/O completions then it will see it as 
completed and this is what triggers the assert. I'll push this for now 
so that Yuri has a fix to work with but I would like to re-visit this 
area again via the master bug.
