No, it's not a bug, it's simply a fact of life for certain kinds of
services: it can take more than 5 seconds to flush all the changes to
disk, especially when all the other services on the machine are shutting
down at the same time.
And yes, a power loss would cause a data loss. That's why such systems
are running from UPS's capable of initiating a shutdown several minutes
before power runs out.
The irony is that Bill Gates claims to be making a stable operating
system and Linus Torvalds claims to be trying to take over the
world. -- seen on the net
