The problem goes as follows:

defadvice looks for the list of args, gets it from the docstring.
It says there are two arguments.  It then generates a wrapper function
that takes 2 args and passes them to the subr.
I.e. from then on any call to sit-for with 3 args will fail because the
adviced function now only takes 2 args rather than 3.
