In fact there is no "system", just some obvious consideration.
As I stated we used Flash to create many small animated windows within a
GUI, and are happy with this, but this can't be considered a GUI system.
Regarding multiple threads (and with this CPUs) driving a rather
standard GUI in parallel, I believe that something like this can be done
using standard GUI libraries (like KDE or GTK, or Windows). If such a
library gets an initialization call from a Process, it can detect the
process ID and the Thread ID. it needs to allocate some memory for the
future work. When we want to use a single GUI per Process and access it
with multiple Threads (which might be forbidden) there would be a single
base of resources per process (and if allowed, the library needs to
synchronize multiple threads appropriately) . If we want to use multiple
GUIs per Process (one per Thread) these resources would need to be
allocated on a per thread base.
I can't believe that the API makers did not consider the two obvious
cases (even though a process with multiple independent GUIs is not a
very common task to do, but obviously the parallel work of multiple CPUs
might speed up things.)
Obviously, if you want non standard speed, you need to consider non
