There is also the case of having persistent coherent buffer mapped with 
one context, and used with another one.
If implementation of coherent requires driver flushes the range at draw 
calls, I guess it may not work as is with the multi context scenerio 
(looking at nouveau, it seems to check if the buffer is mapped in 
current context for example, not for all possible contexts)
