AFAIK, no, although I am doing this somewhat by remote control (I don't have direct access to the failing system).  This did bring up one other question, though:

Are subtransactions written to their own individual reorder buffers (and thus potentially spill files), or are they appended to the topmost transaction's reorder buffer?
