Notes
The problem occurred because the preprocess function was attempting to be serialized when the package
definition is cached to memcache. However, this function is stripped in installed packages;
furthermore, caching "developer packages" (ie unbuilt packages) was never intentional.
This release disables memcaching of developer packages, thus avoiding the bug and bringing back
originally intended behavior.
