+
+/* IMPLEMENTATION NOTE
+
+The goal of this module is quite difficult. We want to have several modules,
+each of them having globals which have to be initialized in any unix
+process. Let's call them world-wide globals. An example may be the messages
+dictionnary, which is world-wide to detect definition discrepencies when
+running in SG.
+
+And then, the module may want to have some globals specific to a gras process,
+just like userdata stuff allows to have per-process globals. Let's call them
+process-wide globals. An example may be the list of attached callbacks.
+
+That is why we have 4 functions per module: the join function is called by any
+process, and is in charge of creating the process-wide globals. If it is the
+first time a process uses the module, it also calls the init function, in
+charge of initializing the world-wide globals. We have the symetric functions
+leave, called by any process not using the module anymore, and exit, in charge
+of freeing the world-wide globals when no process use it anymore.
+
+One can see this as a factory of factories. the init function is a factory
+creating the module, which contains a factory (the join function) able to
+create process-wide globals. The fact that indeed the calling sequence goes
+from join to init and not the other side is just an implementation bias ;)
+
+Then again, we want these functionnalities to be quick. We want to access
+the process-wide globals by providing their rank in a dynar, we don't want to
+search them in a dictionnary. This is especially true in the module
+implementation, where each functions is likely to require them to work. The
+position could be a stored in a global variable only visible from the module
+implementation.
+
+The need for an array in which to store the globals does not hold for
+world-wide globals: only one instance of them can exist in the same unix naming
+space. Thus, there is no need to put them in an array, we can actually declare
+them as regular C globals.
+
+The next trick comes from the fact that the user may (and will) mess up and not
+get all modules initialized in the same order in every process. So, the rank of
+module data cannot be the order in which a process called the join
+function. This has to be a world-wide global instead.
+
+And finally, if we want to get the ability to destroy modules (one day, they
+will load their code in as plugin), we want to give the module handling library
+(ie, this file) to modify the variable containing the rank of module in the
+tables. This is why we have the ID field in the module structure: it points
+exactly to the implementation side global.
+
+Yeah, I know. All this is not that clear. But at least, writing this helped me
+to design that crap ;)
