I'm not familiar with Chaplin's memory management strategy, but in Thorax we automatically manage the lifecycle of child views. If you need to manually manage the lifecycle of views, we've implemented `retain` and `release` methods ala obj-c. It's not an easy subject to tackle in a paragraph, but we've solved the problem enough that we aren't leaking memory in a huge app in a sensitive environment (mobile devices).

Chaplin features this as well, via a "dispose" method. It'd be great to see a comparison list of all these Backbone meta frameworks.

Note: I am just a user of Chaplin, not an author.
