Not sure about what you mean with "blah blah". But given the amount of
both disk caches (metadata, vdb cache) and memory caches (the
in-memory aux_db cache that portage loads using pickle (it's a dict)
takes like 70-100Mb of RAM on an average desktop system), Portage can
still take *minutes* to calculate the merge queue of a pkg with all
its deps satisfied. Ironically, launching the same emerge command
twice, will take more or less the same time.
Yeah, this is probably bad design...
