The problem is that at somepoint filesrc is checking the filesize and it
is not aware that it changes.

You could try using a pipe instead of files (fssink+fdsrc instead of
filesink,filesrc). Otherwise we might need a flag on filesrc to restat
the file for each read and if size changed send a duration change.
