I'd tend to say that the included block should support that. Since
apparently multiple start()/stop() calls by the scheduler is something
blocks should handle gracefully.

I'd assume stop() was made to close the file to ensure the header is
properly written.
But it could just update the header and seek back to the end without
actually closing the file and let the destructor do the close on the
fd.

This sounds like a good idea.
