Can you confirm that we want to ignore the result of
GpuProcessHostUIShim::Create in gpu_process_host.cc:267-268? From the comments,
it looks like the right thing to do but it seems like a strange pattern.

Sorry, thought I LGTMed this already. LGTM.

Ignoring GpuProcessHostUIShim's result is weird but I think it's okay.
