Well, currently an identical copy of the rvm data partition is stored in
memory (swap). So you'd need 315M more swapspace than under normal
circumstances, which I agree is definitely too much.

The RVM stores all metadata, so you would not be able to store as many
files. I don't have the precise calculation here, but I believe the
average filesize is calculated to be around 8KB.
