The trace dies when the traced session dies. I've never heard of a trace being automatically restarted for a new session with the same SID and serial# as an earlier trace, but I've never tested it and I suppose it's possible. On a related note, old trace files will be appended by later traces/dumps for processes with the same PID.  

I just found that in 10g, you can identify active traces by checking the v$session.sql_trace value. This column didn't exist in earlier versions, but the information may have been there in one of the x$ table columns that just wasn't exposed in v$session, or maybe in a different v$ view, but if so I'm not aware of it. In 10g, the v$session.sql_trace value comes from x$ksuse.ksuseflg2, which doesn't exist in 9i.
