Comment (by nacin):

 I was surprised to confirm this, but indeed. The loop occurs in
 wp_kses_named_entities(). The issue is because the global in there is not
 set, and in_array() spins for eternity.

 WordPress is not currently designed to be included from within a function,
 which is your problem, as it sets an awful number of globals, and does not
 make an attempt to ensure that a number of them are indeed operating in
 the global namespace explicitly. If you just include wp-load.php in global
 scope, everything will be fine.

 If you wanted to do this, you can also use something like
 get_defined_vars() and extract everything into the global namespace on
 your own.
