Actually, you might get more efficient swap activity if you have 4 1 GB
swap areas on 4 different devices. That way you're not single threading to
a single device. While you're at it, if you have VM, allocate a VM minidisk
in memory, say maybe 64 megabytes, and give THAT a higher swap priority
than your physical disk swap area.

If all else fails you could always break the partition in halves and
then load both of them as swap dpartitions. You would still have 4GB of
swap space in the end.
