Don,
I agree that the sorting could be made *far* faster.
Thanks for submitting this. We were well aware that the minimal fix for bug
13882 would cause some kind of performance regression, but it was a balance
between a minimal fix and low risk of breakage. I reviewed the patch for 13882
and even build a minimal framework for testing that dynamic loader function
outside of the build.
Do you have the time to investigate this and propose a patch (requires
copyright assignment)?
