debugging patch
This adds some debugging code as well as a simple (but not intended to be the
final) solution to the backend, which for me fully eliminates all "Too many
frags" messages. IOW this might help people here determine whether what they
see is related to the "Too many frags" issue.
A permanent solution will require quite a bit of code re-work, so will take
some more time.
