Both of these are planned for Reiser4.  Or is it 4.1?

I would like said interface to be able to not necessarily flush to disk 
right away, though.  It should certainly be an option (I'm sure MySQL 
would use that option), but sometimes you want the performance, 
especially if there are dozens of these transactions firing all at once 
-- better to let RAM fill up and then flush them all.
