Eh actually yes, this does kindof conflict with work in the bmesh 
branch, where I implemented a vertex array cache system
for meshes.  You might want to look at the work there, as the same code 
can be used in trunk too really.

My solution is kindof memory hungry, but this is done for a reason; in 
my last implementation I tried to use glDrawElements and I ended up 
using a lot *more* memory because glDrawElements couldn't do what was 
needed.
