[linux-help] Re: How to get more virtual memory?

You can also create a swap file without the bother of creating a swap
partition. It is a little slower than a swap partition, but for
a task of a few weeks, it is bearable.  You can also monitor swap
usable while the application is running with the 'top' command.
