I don't know what ifile stores, but if it is anything like inverted
files, another idea would be to use the inverted file compression
algorithms from the Managing Gigabytes folks. I think these produce
machine-independent files, but if not it could probably fairly easily
be achieved.
The idea is that the additional computation spent on compression is
compensated for by the saved I/O.
