Yeah, we have to be careful with any overhead in there, it can be a hot

Could I ask you to rerun the pgbench tests you did recently with this patch?
Or can you think of a better test for this?
I can't do so immediately, because I'm waiting for Nate Boley to tell
me I can go ahead and start testing on that machine again. But I will
do it once I get the word.
I committed this. I ran pgbench test on an 8-core box and didn't see any
slowdown. It would still be good if you get a chance to rerun the bigger
test, but I feel confident that there's no measurable slowdown.
