Can someone provide some background on the GTL giant lock?
What is it? and why was it necessary?

GTL is a language used to implement image filters and such (http://www.opengtl.org/). Apparently it is not thread safe and they needed to block multiple filters from executing at the same time. I think (hope) that this just serializes filters, but that each individual filter can still use multiple cores ?
