The memberOf code is using a single static variable to hold its state. This is 
obviously broken. It's also using thread keys for its temporary storage, which 
is totally unnecessary; it should simply use its own callback and the 
cb_private field of that callback. As such, much of this code needs to be 
gutted and rewritten.
