especially with OSX, where ram is guzzled like no other.

  You sure it's not just the caching tricking you? It's been a long time since I used a Mac but I'd be surprised if it didn't cache as much as possible. Unused RAM is wasted RAM.

    Lion (fixed in 10.8 AFAIK) has a bad habit of preferring to page to the disk instead of freeing up RAM that is being used for caching. I was able to remedy this by using the terminal command "purge" occasionally, and also disabling the dynamic pager[1] [1]http://workstuff.tumblr.com/post/20464780085/something-is-deeply-broken-in-os-x-memory-management http://workstuff.tumblr.com/post/20464780085/something-is-de...

      Lion was absolutely broken in terms of memory management from 10.7.0 through at least 10.7.3sh. (Beach Balls during pageouts, constant memory pressure, weird page-out while using Safari + Aperture - really made me miss 10.6.8) Things got much better in 10.7.4, and 10.7.5 has been so reliable and well balanced that I'm afraid to ever leave it.

      That paging drives me nuts, but nobody seemed to have the same issue. Thanks for posting the helping pointer! (I'm afraid of disabling the dynamic pager, though, as I hit max physical RAM rather often.)
