ubuntu burn-in for new computer?

[taeb]

I've been using ubuntu for a while onan old Mac, but decided I had to
have an Intel machine for it.  My wife and I assembled one this past
Sunday, and I installed Breezy and Dapper-flt5 on it with virtually no
problems.  Runs like a charm, and everything seems to have been found
right off the bat.

Now I would like to do a burn-in by running it pretty hard for an
extended time.  Is there a package that does this, or does one just
compile everything in sight?

Thanks for any suggestions.
