So what does "force to stop" mean in your opinion?  That LilyPond should
refrain from completing the current PDF it has open and make sure that
it is invalid or deleted?  What if the input file generated more than
one PDF?  Should it delete or invalidate the PDF files it has written
previously?  What if it had already written a PDF but fails during
generation of a MIDI or vice versa?

I don't get the obsession with "it is not an error if LilyPond does not
immediately crash and leaves bad output or none at all".

When is a stop forced?  Is LilyPond allowed to produce an error message
before crashing?
