With the latest qemu-kvm.git (fresh pull today, 11-April-2010) the main qemu thread is spinning. It looks like the recent sync with qemu.git is the culprit -- specifically, d6f4ade214a9f74dca9495b83a24ff9c113e4f9a from Paolo on March 10 changed the semantics of main_loop_wait from a timeout value to a nonblocking argument. kvm_main_loop() still invokes it with the argument of 1000 which means the timeout for select is set to 0.
