i think that's a misunderstanding: i think that the priority is low for
the intel device driver developers.
so the drivers are unlikely to be fixed.
from the Gem side i would *love* to have multi-context support (that's
one of the main changes in the last few years!), and consider the
priority rather high.

so if it's fixable on the Gem side, it shall be done.

anyhow:
there is a bug in current Gem that prevents multi-window support in
non-context shared environments. if this bug was fixed, [gemglxwindow]
could be compiled without context sharing support and still allow
previewing in a separate window (though less performant).

finally:
afair glfw3 has support for context-sharing, and it (the glfw3 demo
showing this feature) doesn't seem to crash on intel cards.
which hints that the bug is really with Gem (not the drivers).
i can't remember the state of the [gemglfw3window] regarding context
sharing.
