I disagree. But of course, it's so obvious to any Real Programmer that
you must be right and I must be wrong that it would be quite
unreasonable to ask you to justify your claim.

All I see there is yet another bare assertion that race conditions exist
with no attempt to back it up with logic. And some broken code.

I'm giving up on this whole thing as of now. You've made it totally
clear that your mind is made up and you aren't prepared to engage in any
sort of discussion. I'm going to stop beating my head against a stone
wall and go do something more productive.
