Thanks for pointing that out. I just checked the size of bundle 100 and =
just on my pretty empty test
database that I run locally and delete every so often, it is 1.5GB!

$ du -d 2 -h felix-cache/bundle100/
1.5G	felix-cache/bundle100//data/tdb-data
1.5G	felix-cache/bundle100//data
 16K	felix-cache/bundle100//version0.0
1.5G	felix-cache/bundle100/

So for the Social Web applications I am working where I would like to =
work with a lot of graphs, this is not good. I'd like to know the reason =
for this. But it does look like a reason to switch to Sesame =
otherwise...
