"One example user of worker threads is posix-aio-compat.c, an asynchronous file I/O implementation. When core QEMU issues an aio request it is placed on a queue. Worker threads take requests off the queue and execute them outside of core QEMU. They may perform blocking operations since they execute in their own threads and do not block Another example is ui/vnc-jobs-async.c which performs compute-intensive image compression and encoding in worker threads." I wonder why there isn't a general framework for this? Some thread that would take requests off a queue and process them without knowing the internals of the request.
