Mind taking a look or helping to route this, sugoi@?  Thanks!

This is just a regular out-of-memory situation. We could use nothrow to silence the exception, but then we'd probably just crash on accessing the null buffer. We have no immediate intention to harden against every possible OOM. Crashing the GPU process is reasonable under exceptional situations like these. OOMs caused by leaks or allocating too much memory are a different story of course.

So I'm inclined to close this as Won't Fix.
