Fixed disk result in these pieces of information being cached. I thought this problem had been solved since at least 2000 (when LifeKeeper ran into the same issue) by sending the BLKRRPART ioctl to the device ... whether removable or not, this forces a reread of all the vital information (always providing nothing has the nodes open, of course, we can't physically yank the information out of applications using it). If there's something BLKRRPART isn't doing we can probably fix it ... that's certainly better than lying to the kernel about the devices.
