marginal
1. Extremely small. "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 extremely small merit. "This proposed new feature seems
rather marginal to me."
3. Of extremely small probability of {win}ning. "The power
supply was rather marginal anyway; no wonder it fried."
