Detailed description

A method call takes 20-40 times longer when advised.

Method aliasing takes about 2 times longer.

Some possible bottlenecks:

1. The Proc array. If we make unadvising optional, then we can simplify this structure.
2. Also, if there is only one advice on a join point, then we could simply use alias_method. We could start with this as the default, then replace it with the fuller implementation if a second advice is applied.
