Hey Alasdair.

My changes to make it compile using gcc 4.7 was identical to your (except for a 
version test)

I'm currently using Debian Squeeze and after upgrading to revision 131, the 
pipeline_test hangs infinitely. I haven't tracked down why - I spent a fraction 
of my spare time on generalizing the usage of gcl to GPUs using OpenCL (using 
the C API of course)

Hi Jens,

The pipeline code needs to be re-architected at some point. It doesn't handle 
threading very efficiently (it typically spins up more threads than are 
necessary) so we haven't put a lot of work into making the current code 
perfect. Our focus was more on the API.

That said, it wou,d be good to work out what's going on. Do you have any kind 
of thread dump from when it hangs?
