I'm getting around 23 seconds with DMD 2.059 and around 9.5 seconds 
using DMD 1.072 with Tango. I'm compiling on Mac OS X 32bit.

So using Tango is a around 2.5x faster than using Phobos. But it's not 
in the same league as msgpack. It's not even in the same sport :)

I'll see if I can to something about it.
