Why?
Because the queue output and draining, AFAICS, is implemented in a blocking manner.
When non-blocking mode is set (see snd_seq_nonblock()), snd_seq_drain_output() does not block but writes only as many events to the kernel buffer as fit inside (or returns -EAGAIN if the kernel buffer is completely full).
