Afaik the cleanup of the cached data when files get deleted or projects closed
is far from optimal currently. Keeping the cache with the project cannot be
done as the same project could be opened in multiple sessions (and no, the
cache is not multi-process safe).
I fear, for now, you'll have to live with the current situation. But what do
you mean by "multiple 200Mb-code projects don't fit into one session"? Is your
hard disk too small to hold the cache? Having the projects in multiple session
won't change much in that regard.
