Some APIs are session-based. Those give the user an object that lives
through the session and needs to be disposed at the end. On the case of
VC or Magit, Emacs would request from libgit2 to work with a given repo,
operate on it and close the session. That means that if the user kills
the magit-status buffer that was visiting a repo, the associated session
object must be closed (this is a simplistic scenario, in practice things
are more complicated.) It would be nice to explain how to handle this
use case on a robust way (the failure to properly close a session,
transaction, whatever on some packages can produce very annoying
consequences.) How objects created by the module system interact with
garbage collection is an start.
