[suggestion] mmap.js

I know one the vital points of Medea is the fact that it's js only, but perhaps this could still be interesting:

If one day such an API lands in the node core - or even it doesn't - this is still interesting to experiment with when it comes to data storage systems.

@Ivshti In the early days, I did an experiment adding mmap support to Medea (for reads only). In the benchmark comparisons, it became very clear where LevelDB was getting its speed boost on reads.

I wish mmap support were in the Node core. I know this goes against a lot of popular opinion, as most folks prefer to keep the core of Node as small as possible. However, mmap would have been stellar in this all-JavaScript library. We run Medea on constrained platforms like the Beaglebone Black and enjoy the rapid speed-to-satisfaction that comes with no compile time on npm install.

For now, I think there'd have to be a medea-mmap module that wraps medea with mmap support. That would be pretty rad.
