If you have some storage room available on another filesystem, create
some swap space. I've done it once on a 1 GB RAM machine (adding up 8
GB of swap). The repair will be much, much longer but it works.

To create 64GB of swap space in a file, do something like this:

dd if=/dev/zero bs=1M count=65536 of=/some/file.swp
mkswap /some/file.swp
swapon /some/file.swp

However preferably don't use a single spinning drive, it's much too
slow. Flash devices are to be preferred, even a good quality USB thumb
drive will do.
