marginal: adj. [common] 1. [techspeak] An extremely small
change. "A marginal increase in core can decrease GC time
drastically." In everyday terms, this means that it is a lot easier
to clean off your desk if you have a spare place to put some of the
junk while you sort through it. 2. Of little merit. "This proposed
new feature seems rather marginal to me." 3. Of extremely small
probability of winning. "The power supply was rather marginal
anyway; no wonder it fried."
