/* Thread support

* ==============

* The python interpreter has a global interpreter lock. Any thread

* executing must acquire it before working with data accessible from

* python code. Here we must also care about xchat not being

* thread-safe. We do this by using an xchat lock, which protects

* xchat instructions from being executed out of time (when this

* plugin is not "active").

* When xchat calls python code:

* - Change the current_plugin for the executing plugin;

* - Release xchat lock

* - Acquire the global interpreter lock

* - Make the python call

* - Release the global interpreter lock

* - Acquire xchat lock

* When python code calls xchat:

* - Release the global interpreter lock

* - Acquire xchat lock

* - Restore context, if necessary

* - Make the xchat call

* - Release xchat lock

* - Acquire the global interpreter lock

* Inside a timer, so that individual threads have a chance to run:

* - Release xchat lock

* - Go ahead threads. Have a nice time!

* - Acquire xchat lock
