Use pmset to restore your Mac's instant-wake after upgrading to Yosemite

I just upgraded to Mac OS X Yosemite Beta 3, and sure enough, Apple has once again broken my time-to-deep-sleep setting. After I upgraded, I noticed that my computer took a few seconds to wake from sleep, rather than the usual instant-on that defined OS X for so long. I checked pmset, Mac's power management command-line utility:

sudo pmset -a standbydelay 86400
