The overhead of per-context pointer switching will be there. The
question is, make it inherent to the API, or is it something the
application has to add when needed. This is a call-intensive
API, if another indirection becomes mandatory even for a
single-context application, it might hurt? I can understand
that people maintaining a dozen contexts would rather have
this convenience, but there are also games, and the ones I
have dealt with already have a lay that could easily handle 
this case for multiple contexts (w/o another indirection even).
