Flushing Large Geom During Renders

[aracid]

hey all

trying this crowd thing and alls good until i try push more than 500 people

and then my render result in massive memory usage, 2000MB+

my buckets are down to 16, and i never really load the same piece of geom more than 2 or three times,

is there any way to flush the memory during renders?

or better yet, to force mantra to "release" the geom once it has been rendered?

Crowd WIP

thanks in advance
