In KVM, we sleep for 1s in select() and use signalfd() to receive the aio notifications. For older hosts, we emulate signalfd using a thread and the pipe-to-self trick.

Why does it need a thread ?  You can just write to the pipe in the
signal handler.  I'll post my code.

Not sure that it matters, but the semantics are slightly different: with a thread you don't get EINTR in random syscalls as the signal thread is the only one that has the signals unblocked.
