1. A system comprising:

  • at least processor;

    a standard interface for at least one standard procedure;

    a non-standard interface for at least one non-standard procedure that is not natively supported by said standard interface;

    an interposer for intercepting procedure calls made to said standard interface and determining whether an intercepted procedure call is for invoking one of said at least one standard procedure or for invoking one of said at least one non-standard procedure, wherein if said intercepted procedure call is for invoking one of said at least one standard procedure said interposer directs said intercepted procedure call to said standard interface and wherein if said intercepted procedure call is for invoking one of said at least one non-standard procedure said interposer directs said intercepted procedure call to said non-standard interface;

    an index, comprising less bits when identifying said one of said at least one standard procedure than when identifying said one of said at least one non-standard procedure, included in said intercepted procedure call to identify a procedure to be invoked; and

    wherein said interposer determines from said index whether said index identifies said one of said at least one standard procedure or said one of said at least one non-standard procedure.
