`LaTeX-verbatim-p' looks first at the face at point, then to the
current macro, and if all previous tests are nil, which is the most
common case, runs also `LaTeX-current-environment', which is known to
be *slow*.

I think current parsing time is acceptable, less than 0.1 s in your
long and complex document is reasonably low, and I hoped that there
were already the test for verbatim mode.  But since this test is not
there, adding it wouldn't be a fair trade-off.
