Isn't that a good thing though?  On a multi-user machine, you don't
want a single process to just grab every single processor without any
regard to interactive performance.  We have had several problems on
our site with FASTA destroying interactive performance on our main
machine, which also has to function as a mail host for 1500 people.

It seems that under IRIX 5 at least, fasta has a tendency to grab 80%
CPU even when niced as much as possible, which is just terrible.
