magit, revert, folding, normal-mode, performance

Worth knowing that magit reverts buffers.  It appears to
revert all buffers, not just those with changes.  This has 2
consequences for org.  Magit is slow, and org visibility is
reset to default.

So I wonder:

Is there a way to preserve visibilty across revert-buffer?
Has anybody profiled loading a large org file?

Thanks.

Magit reverts all saved buffers on the current working copy after
committing.

I'm the author of the patch that introduced that behavior on magit. The
purpose is to update the VC modeline text that indicates when a file is
edited (Git-branch_name for pristine files, Git:branch_name for edited
files.) It's true thas sometimes reverting can be slow and produce side
effects.

I'll look at the docstring of `revert-buffer' and, specifically, to
`revert-buffer-function'. But don't bother, I have a patch for updating
the VC modeline without reverting the buffer and will submit it to the
magit mailing list right now.
