That's only true if the lifetime of the pool (or object) is the same as
the lifetime of a block of code. If that's not true, then you're back
to remembering to do an explicit delete.

I'll buy that, but there is still an efficiency concern if this decision
reaches fine-grained interfaces like strings. Putting each svn string
in its own APR pool means spending 8K per string, which is pretty bad if
the application uses a lot of them.

(I'm not really sold on APR pools in the first place, but it's a maybe a
tiny bit late to think about going back on that.)
