P.S.  Unfortunatey, I cannot fix the performance issues
regarding vertical cursor motion, this is in the guts of
Emacs.  `C-c C-f' and `C-c C-b' do help a bit...

It is funny that outline-previous-visible-heading is faster than
previous-line when the previous subtree is folded.  I wonder if Emacs
searches for bol when it should be searching for visible text first,
then bol, or something.

WHen Emacs does `previous-line', it does line by line, moving
on when the line is invisible. C-c C-b search headlines by regexp
and check only the headlines for visibilitiy.
