It turns out file descriptors cannot be polled on Windows, so apr_file_pipe_create() is out. APR has a Windows-only function called apr_file_socket_pipe_create(), but it's private to the implementation of apr_pollset_wakeup(). So apr_pollset_wakeup() it is. (I would prefer to use apr_file_socket_pipe_create() myself -- my current solution has the theoretical problem that the wakeup pipe could fill up, if clients send messages fast enough that poll() is never called.)
