----------------------------------------------------------------
Here's the patch.
I'm somewhat concerned however about the threading issue mentioned.
Following the code as it is, my understanding was that configurations are going
to get run through doLoad in AbstractConfigurationProvider, which is thread
safe. Please correct me if I'm wrong on that, and I'll fix the issue.
As far as the disallowing of the capacity resizing, that could be a valid
concern though it would make the simple code more finicky. I guess it depends
on how important others feel it would be to others, I can revisit this if
people feel it's a big deal.
