The option it to wrap the attached mixin methods so each class including 
the mixin points to a separate function. This is actually implemented in 
the framework since rev. 13972. Since it causes some overhead it is only 
applied if qx.Class.patch is used. See bug #323 
<http://bugzilla.qooxdoo.org/show_bug.cgi?id=323> for details.

Calling "this.base(arguments)" from a mixin member will call the 
overridden/patched member in the class including the mixin.
