Not that I can think of.  Other problems with the help system are 
presentation, mostly.

No, unfortunately.  It uses the Catalog, which is based on ZODB, and it 
puts a Catalog instance into the main FileStorage, which is undoing and 
versioning.  It then proceeds to do writes to the database when it 
appears that all you're doing is reading a pre-existing page.  If you're 
in a version at the time, a set of objects will be written into the 
Catalog and into other places in instance space that  have version. 
This is a bad pattern, and the only way to fix it is to prevent it from 
happening, which requires some helpsystem architectural changes that 
amount (IMHO) to a rewrite.
