I think you may be doing this person a disservice with that advice
without first understanding more about what he is trying to
accomplish.  I can off-hand think of several scenarios where it would
be far most cost effective to optimize the memory usage of an
application, rather than throwing more memory at the problem;
Conversely there are times when it makes sense to just load up more
memory.

An example I'll throw out is the case of VPS hosting.  You have a
server, wholly yours, but no physical way of adding RAM to it.
Possibly to upgrade the amount of RAM you need to upgrade service
(check slicehost.com - that is their business model).  So you could
see a model of $40/hour or programming to solve for optimizing memory,
VS. $40/month for more RAM, estimated 12 months run of project and 4
hours spent on optimization = $160 of programming time to $480 ($40/mo
* 12 months) of increased operational cost = $320 net savings.

Anyway, I don't know how to fix for the original problem asked, but
let's not spit out "throw more hardware at the problem", until we
understand the problem.
