Funny, I've been trying to write at least a REQ_TASK_ABORT handler all
week. I'm having a bit of trouble using the transaction context...
mostly because the value I'm getting doesn't correspond to any ascb.
Assuming, of course, that ascb->scb->header.index/ascb->tc_index are
indeed transaction contexts.
