Release models make a huge difference in the properties of the software delivered. I believe there is no single "ideal" model; what to choose depends on the code base, the group/community creating the code, the users/customers, the technology available (languages, CI tools, others)... What works for Hudson does not work for GlassFish nor for Solaris.
MySQL is changing its release model to improve agility, quality, predictability and facilitate contributions. Giuseppe just posted an Overview; in a nutshell, the trunk tree is always in beta quality, new features are first developed in stage branches, then integrated into the trunk, which is then brought to RC quality and another cycle starts (see Diagram).
