You're right, the bottleneck in `LaTeX-verbatim-p' is
`LaTeX-current-environment' which performs multiple searches, but is
also capable to determine outer environments than the innermost one.
We could use a simpler version just for `LaTeX-verbatim-p' (we do need
the innermost environment there), though I'm not sure doing the whole
search in one shot would improve performance, but I didn't test.

Bye,
