It is protected by a mixture of reference counting, thread-local storage and careful coding to take care of re-entrancy. I'm not too sure that we can use it, though. Mostly because of the reasons Jan mentioned (it may also not be precise enough, but we can fix that with our own GSource wrapping POSIX real-time timers or Linux timerfds). Paolo
