Comment (by jrf):

 Note: what about introducing a `wp_is_function_disabled( $function_name )`
 function (better names welcome) ?

 I know there are several places in the code base where function checks are
 being done as misinformed hosts have a tendency to disable those
 functions.

 Now might be good time to streamline those checks throughout the codebase
 to ensure the verification of the callability of the potentially disabled
 functions is done consistently.
