Which has been answered from a long time already.

For the technically minded, you "just" have to rewrite the
rendering engine so that no global/static variable is used with
write/modify access. The bad news is that it is only the first
step, and that there is a lot of such variable/arrays,
specially as optimisation of some patterns and computation
of shadow & reflection.

The following steps introduce non-portability unless

you restrict portability to something like Posix thread
compliant systems (or whatever you choose for multiple processors).
Anyway, it is bad...
