+/* In order to understand what the heck is going on with the
+ * mansession_session and mansession structs, we need to have a bit of a history
+ * lesson.
+ *
+ * In the beginning, there was the mansession. The mansession contained data that was
+ * intrinsic to a manager session, such as the time that it started, the name of the logged-in
+ * user, etc. In addition to these parameters were the f and fd parameters. For typical manager
+ * sessions, these were used to represent the TCP socket over which the AMI session was taking
+ * place. It makes perfect sense for these fields to be a part of the session-specific data since
+ * the session actually defines this information.
+ *
+ * Then came the HTTP AMI sessions. With these, the f and fd fields need to be opened and closed
+ * for every single action that occurs. Thus the f and fd fields aren't really specific to the session
+ * but rather to the action that is being executed. Because a single session may execute many commands
+ * at once, some sort of safety needed to be added in order to be sure that we did not end up with fd
+ * leaks from one action overwriting the f and fd fields used by a previous action before the previous action
+ * has had a chance to properly close its handles.
+ *
+ * The initial idea to solve this was to use thread synchronization, but this prevented multiple actions
+ * from being run at the same time in a single session. Some manager actions may block for a long time, thus
+ * creating a large queue of actions to execute. In addition, this fix did not address the basic architectural
+ * issue that for HTTP manager sessions, the f and fd variables are not really a part of the session, but are
+ * part of the action instead.
+ *
+ * The new idea was to create a structure on the stack for each HTTP Manager action. This structure would
+ * contain the action-specific information, such as which file to write to. In order to maintain expectations
+ * of action handlers and not have to change the public API of the manager code, we would need to name this
+ * new stacked structure 'mansession' and contain within it the old mansession struct that we used to use.
+ * We renamed the old mansession struct 'mansession_session' to hopefully convey that what is in this structure
+ * is session-specific data. The structure that it is wrapped in, called a 'mansession' really contains action-specific
+ * data.
