Other than that, I'm assuming that checking for address space matches
between two direct contexts is handled by the client side (I think I
recall code to that effect, and seems like the only possible place),
Indirectly. Assuming an application is using libGL (and not rolling its
own GLX protocol), the only way to get a context from another process is
via glXImportContextEXT. This function is supposed to fail for direct
rendering contexts (with GLXBadContext), and our implementation does.
We have some other bugs in this general area on the client, but I should
have patches for those in the new year.
