You simply can't have functions that can be called both
with or without the GDK lock, so you need to decide in
which category your function lies, and code accordingly.

(It's generally pretty much needed for any thread programming
to know what locks you have at every point in your code ..
if you don't know that information, it's hard to avoid
deadlocks.)
