Comment:

 I have tested this against Wordpress 2.8.4 on a large site that is soon to
 be released.

 The $join on line 1925 is not needed (it joins the taxonomy and term
 tables on when they are not used in the WHERE). Removing it speeds things
 up considerably, especially on installs which have thousands of terms.

 Attached patch simply removes said line.
