Needs to save references to nextTick and friends to avoid side-effects from stubbing

[fatso83]

We got a bug report our way in sinonjs/fake-timers#66, which basically boils down to that tape ends up using stubbed timing functions and gets stuck. Mocha solves this issue by saving references to all global timing related functions, such as setTimeout, setInterval, nextTick, ..., so that later modifications will not interfere with its internal use of them.

This would be the easiest fix.

Relevant lines that uses nextTick:

• example 1
• example 2

Yeah, seems like a reasonable way of resolving this - though one might also argue that clocks should never be messed with. But it probably has its uses, so hey

Absolutely tape should be robust against modification of globals - thanks for the report!

Please file one on through for dominictarr/through@903501a#diff-168726dbe96b3ce427e7fedce31bb0bcR49 - that's a separate repo.

Your given example though is indeed a cached version of process.nextTick - there's one example of setTimeout in tape code, which I'll fix shortly.
