My intent wasn't clear. What I meant is that if there is a gap in the
middle, then it should be filled (there may be some consideration of
resizing efficiency, or none) - it's not a question of whether or not a
delete has "ever" occurred. So if there is no gap - then the insert is
at the end, and if there is a gap - it should be filled.

The indexes DO change, but iterators and references should probably
remain unchanged...

I've looked at the implementation of the circular buffer that Pavel has
posted a reference to - and it does not fulfill the above requirements...

Thanks again for the comments.
