Hmm, you might want to play around with the -rvmt flag for venus then. 

If you use a ram-drive for the cache, you can use RVM in degraded mode.
"-rvmt 3" will not use a backing file on disk to persistently store
changes. It is like always starting venus with the -init flag. And the
data will not be in memory twice (once in the ramdisk RVM data file and
once in Venus's memory).

Interesting, but don't you then get a chicken or egg problem when the
power fails ;)
