What is the efficiency difference? Can it be reduced?

Appender is currently much faster than array appending because it has a
dedicated place to store the array length/capacity. Simply wrapping arrays
makes it much slower (which has a necessarily very convoluted way to lookup the
block capacity). Or am I missing something?

Subject: Re: [phobos] Clear appending cache?
Related question: can we make Appender a thin wrapper over arrays? It
looks like improving "~=" caching is the right way to place effort.

Can someone who knows better than me how it works (probably Steve)
please put a function in druntime to clear the current thread's array
appending cache? I need this for two reasons:
1. To make sure arrays I'm done with get GC'd.
2. To make it safe(r) to free arrays manually.
