The big problem there is threads. We simply cannot have different VM
setups for different threads of a given process --- threads are
_defined_ as being processes which share the same VM. The only way to
achieve VM serialisation in a threaded application via the scheduler is
to serialise the threads, which is rather contrary to what you want on
an SMP machine. CivCTP and Quake 3 are already threaded and SMP-capable
on Linux, for example, and we have a threaded version of the Mesa openGL
libraries too.
