There are very little platform specific notes in the regular
documentation. Tbe best sync settings for performance and safety tend
to differ on various platforms.
There is a win32 faq; in the current state of things win32 specific
notes belongs there. I think a reasonable case could be made to move
various platform specific things into the regular documentation in a
special section.
