Okay, thanks. But that probably won't help that much. We need to figure 
out where the difference comes from.

monotone's cvs_import also stores the deltas in it's database, before 
all of the toposort stuff. Only blobs and their dependencies are kept in 
memory. The filenames as well as the revision strings are only stored once.

I suspect the internal storage format of the cvs events can be 
optimized, though.
