It's possible. I'm not certain that that is really what you are

I doubt we'd consider patching such a problem in 7.4. At this point
the only issues that will get patched in 7.4 are security and data-loss
risks, not performance problems.
Again: demonstrating the issue in 8.1 or CVS HEAD would be a good step
towards getting people motivated to fix it.
