(Get the code!)
I could not reproduce this at first using a loop device, but then I tried scsi_debug. This can be reproduced with a simple dd if=/dev/zero count=0 of=/dev/sda. Parted takes care to not needlessly delete and recreate partition dev nodes when they are not modified, but it appears that there has been a regression in udev/systemd that deletes and recreates all partitions on the disk any time the disk is opened for RW access, thus resetting the RO flag, and also triggering needless update events that cause unity to re-add removed drive icons to the launcher.
