Maybe I didn't, busy as hell happens a lot these days.

That question made perfect sense to me. Putting a global resource in

Look, I merely reminded Tehun that the problem had never been resolved.
I was asked to post, and did that. Don't get upset with me for posting
the solution I like best. If I weren't taking the bug seriously enough
(small as it is), I wouldn't have reminded Tehun.

I fixed my customers problems the global way months ago, could have and
likely should have ignored the fact that buglet lives on in mainline.
