Yes it does. Because it basically hides everything that happens inside
the lock, which is what causes the contention in the first place.

So stop making inane and stupid arguments, Dave.

Your profiles are shit. Deal with it, or accept that nobody is ever
going to bother working on them because your profiles don't give
useful information.

I see that you actually fixed your profiles, but quite frankly, the
amount of pure unadulterated crap you posted in this email is worth
reacting negatively to.

You generally make so much sense that it's shocking to see you then
make these crazy excuses for your completely broken profiles.
