The GCoroutine API has a very direct mapping to QEMU's coroutine interface: https://github.com/elmarco/gcoroutine/blob/master/src/gcoroutine.h I like that you added gpointer arguments and return values to enter/yield. When writing the QEMU coroutine interface I dropped them because I felt we wouldn't need them, but they are appropriate in a general-purpose coroutine library. Kevin Lieven and Peter Lieven are currently measuring and improving coroutine performance in the QEMU block layer. I guess this will result in code changes to QEMU's coroutines implementation over the next weeks. Stefan
