unwind panics instead of aborting the process

Browse source 
a panic in a session task now kills that connection, tokio catches it and the
accept loop carries on. with abort it took the whole server down.

the data table RwLock is std so it poisons on panic, and every lookup went
through expect(). one panic would have bricked every later table read, which is
worse than the abort was. it reads the inner value now, the table is read only
once installed.
