Sounds fair, I havn't used more than about 2Gb of my 4Gb that I have
noticed, despite firefox's best efforts.

BTW what are the restrictions on what Python can be used when Geany
calls a Python callback, I guess everything has to be a function that
runs to completion.  Can it be a closure, can it use yield, can it use
threads, can it do async I/O so as not to block Geany?
