Hi,
I'm currently working asynchronous-encoding for the VNC server and
using that kind of approach (a queue of jobs, with a worker thread).
I'll post a RFC patch soon, but I would be happy to move to a generic
solution instead of managing my own queue of job.

I noticed that you were using directly pthread_* functions. Maybe you
should use (and extend) qemu-thread.h to provide some
kind of thread abstraction (even if currently qemu-thread is a direct
wrapper to pthread).

Thanks,
