[SuicideJunkie]: So, possibly interesting thing; I had that script which was using more than all the ram to open an absurdly large spreadsheet. I set it up to spin overnight nightly, so it stopped releasing memory since it was never fully exited.
[SuicideJunkie]: Didn't expect that to be a problem. There's plenty of disk space for swap, and the memory space would be reused the next day. But apparently virtualbox dies with a guru meditation when there's no physical memory unused on start.
