Oh wow.  This one is seriously annoying.  If you take out all
\stopStaff, it is apparent that the TabStaff is alive through the whole
piece.  This is also the case when replacing \new Line with \new
StaffGroup.  This is something like the "the first new context in a
group is kept alive" rule.  If you replace

    \new TabStaff ...

with

    << \new DevNull {} \new TabStaff ... >>

the problem goes away even without \stopStaff.  But that's seriously
messed up.
