The only way I have ever been able to exercise this is by
using the scsi-debug fake host adapter, and by then running all of the
scsi code in user mode under gdb. Crude, but before I was able to do
something like this, the abort/reset code was completely useless.

Yeah, I saw it, but I have been kind of busy.
