In fact,

I've just found that xc/programs/ico has a multithreaded option.

It fires up no problems with -threads 1. So I know the function pointers 
are now working.

But, sadly when starting two threads there are problems. This is more likely
to be with the pthread support though. It's looking like the first thread
is grabbing events from the second. Possibly some race condition. Although it's 
complete speculation at the moment, just the way it looks on screen. It does
eventually crash due to the other thread grabbing one of the others event.

Rob - If you start 'ico -threads 2'  you'll have a good test case for when
I've cleaned up the mutex's.
