Hmm, ok.

Since this is not closed as INTENDED, I assume there must be another solution.

A) Keep the current swapBackingFile etc. mechanisms and make a backup file
condititonally, like in #23:

> I wanted to suggest a size limit for such a backup, which could be linked

> * Low: Backup files below 2MB; if they are not in the home directory
> below 10MB
> * Normal (default): Backup files below 10MB; if they are not in the home
> directory below 20MB
> * Agressive: Backup files below 50MB
> * Greedy: Backup all files which fit into the free memory
(Remote files are always backed up, because of ReadOnlyPart.)

B) Disable editing tools (annotations, forms) when the file is not a remote
file.
