Stream devices assume that all QXL devices are registered with the
server before we receive any communications from the stream device. This
is due to the fact that QXL display channel IDs are assigned directly
from the QXL device ID, whereas Stream display channels are assigned
channel IDs based on the next free ID. If the stream channel is
created first, it will find that 0 is the first available display ID and
use that for its channel ID. Then when QXL device #0 is registered, it
will also create a display channel with channel ID 0, and they will
conflict.
