True, but running out of memory is, in traditional Unix, an irrecove-
rable error condition, and if it occurs in the kernel, its only option
IS, in fact, to panic. (OOM killers, as Linux has had recently, can be
the worse way out, in fact.) While it should probably refuse to operate
or rollback or not offer read-write access, this is understandable.
Finally, while you don't have to USE it, you may want to have the abi-
lity, if not for reading data from a medium using it.
