Hi, I also just suffered this problem in Natty. Memory usage peaked at over 12gb virtual and the operation lasted for over 10 minutes. The memory situation resolved after this time with the udisks-daemon process ending, but palimpsest indicates that it's still waiting for the bootable flag operation to complete by the spinning circles in the partition. The partition was mounted at the time. I was trying to invert the bootable flag state, i.e. for device sdb1 to have 'bootable', and for device sb2 to not have the flag.
