/* 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
*
