Also, we intentionally keep a pool of worker threads, in order to minimize the overhead of creating and tearing down threads; the pool is populated on demand. If there is a free thread, we reuse it; otherwise we create the new one. A thread that has nothing to do is not wasting resources while waiting around for a new reason to be used. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
