--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
One observation about the mmiotrace... grepping for PDISPLAY (and MARK), I see
the following sequence after the replug happens. I don't know of anything we
have any code to reproduce something like that. It also looks like the blob is
using PDAEMON to do a *lot* more stuff now...
