The procedure unprofile alters the given profiled procedures to their original state before they were profiled.

If no procedures are specified, all procedures currently profiled are restored to their original state.

When a procedure is unprofiled, all runtime information for that procedure is lost.

If unprofile is successful, it returns NULL on exit.
