... which actually make more sense since a "flush" shouldn't close the 
actual handle, well that is common knowledge. I'll revamp this tonight 
to only do the flush.

In addition, I've done extensive searching for code examples (everybody 
discussing this is confused, as you rightly pointed out) and from the 
eaxmples I've seen it still keeps the key open after a flush.
