Also, I think there is a requirement in PCI that says that masters and
targets are not allowed to condition their assertion of xRDY based on the
other guy's xRDY, i.e. a target cannot wait for the master to assert IRDY
before asserting TRDY and vice versa.  I didn't look it up but I seem to
remember it.
