[I'm just confused trying to follow the argument.  Feel free to ignore.]

Aren't there two issues here?  One is resynchronizing
the message stream, so that both sides agree on the 
message boundaries.  The other is resynchronizing 
the 9P conversation state, so that both sides agree
on which tags and fids are in use and what they mean.

Something (an underlying transport protocol, say) needs
to provide the first capability, but without the second
you're still hosed.  In an IP environment, you can drop
and redial the connection, but if you've got a hard-wired
link, you need an explicit restart within the protocol,
hence Tsession, no?
