We're having problems using mocker under python2.6, and it seems like the problem may be related to "Patch #1700288: added a type attribute cache that caches method accesses, resulting in speedups in heavily object-oriented code."

[Gustavo Niemeyer (niemeyer)]

The reported problem in the test suite which is seen in 2.6 has been fixed in trunk already, and will be out in 0.15.
