Would a more thorough explanation help?

If not, I'll just switch to your suggested variable name. I think
either "svn_swig_pool" or "svn_swig_py_pool" would be good names.

All the code which currently uses this application-level pool is
Python-specific. Nevertheless, we also define function-level pools in
all three languages, and these pools use the same variable name. I
think that this consistency is a Good Thing, because, with consistent
variable names between bindings, we can (theoretically) write code
which works with all three sets of bindings.

It's not often that it is possible to reuse the same code for
different sets of bindings, but when it is possible, it helps reduce
maintenance costs.

So, to summarize, I'm leaning towards using the name "svn_swig_pool".
