That doesn't change anything to the fact that calling something like
sit-for from within a with-silent-modifications is a problem, regardless
of buffer-file-name.  E.g. it will cause the process filter not to mark
the new text for highlighting, so it can screw up *compilation*.

Of course there is.  I know there is no error signaled, but you can
still get a backtrace by calling (backtrace), or (debug).
