Contexts are usually terminated at the first musical moment in
which they have nothing to do. So @code{Voice} contexts die as
-soon as they contain no events; @code{Staff} contexts die as soon
-as all the @code{Voice} contexts within them contain no events; etc.

This can cause difficulties if earlier contexts which have died
