The right place for this is geom_disk.c:g_disk_start() and the start
routines of the drivers which do not use geom_disk.

The easiest way to handle it would be to set a flag on the g_provider
saying "no more", have g_down spill the requests into a side queue
and when the driver is ready again, it calls some function which 
pulls the request out of the side queue again.
