Better yet, we should look at using GThreadPool to replace posix-aio-compat.
When interacting with the thread pool is part of some time-critical path

In certain circumstances, posix-aio-compat can incur a lot of latency:
- threads are created by vcpu threads, so if vcpu affinity is set,
aio threads inherit vcpu affinity. This can cause many aio threads
to compete for one cpu.
- we can create up to max_threads (64) aio threads in one go;
