Comment (by snburkett):

 Let me clarify that last comment...  we are actually okay on our
 standalone scripts, the real problem is that I need to call a function
 that accesses the database before wordpress loads - which requires
 apply_filters to be defined.  So I can define apply_filters as a no-op.
 But then once we continue on and allow wordpress to load I get "cannot
 redefine".  It's a weird situation I know, but important for our plugin.
 The only solution that I can come up with short of reinserting the
 function_exists check in the wordpress core would be to use runkit to
 undefine the function after I am done processing - but I am loathe to be
 dependent on runkit.
