I think just recording pid at create as opposed to the last exec would be fine -- my DRI2 buffers are charged to the X Server, my 3D client buffers are always charged to it, and batchbuffers are always the client that execced it because they're not shared. I've definitely wanted this in the debug info, and written a hack like this (but worse) before.
