I FINALLY researched this extensively.  The problem is that, except for
IOS-XR, single-connection does not work, period.  And, Cisco told me that
they would not fix it.

Note that the tac_plus daemon does not support it anyway; I'd just jammed
basic debugging code into it.  I don't know if I'll add it in the future.
