Not sure why calculating outdated packages takes so much memory. Does
the same happen with 'port outdated'? Basically this should be the same
calculation.

I experience something like this, but only when port does (de)activate.

I was not able to track it down further, but tclsh often takes up to
350-400 MB of RAM for me. I don't know if it has something to do with
the number of ports installed, as I can't reproduce it with a clean
install. In this installation, I have >600 ports installed.
