Faster Mac Suspend/Resume

If you have a relatively recent OS X laptop, the default when you close it is to save your current state both in memory (fast) and to disk (slow). This way you get fast startup from memory, plus if you totally run out of power the disk saves your state. This is generally okay but one problem is, if you open and close your laptop several times in fairly quick succession, while it still seems to be busy writing to disk, this sometimes beachballs the laptop for a minute or so while it figures things out.

So if you basically never run your battery down all the way, you don't need the slow disk suspend. You can actually shut this off.

Thanks to ongoing for the tip.
