Memory leak

[gjohnson]

I am still tracking this down, but I am pretty sure the memoize stuff added in 803d2e2 introduced memory leaking. If you need to format a million unique dates, it's basically going to cache all of them and never let go.

it's a pretty bad memory leak and caused us to stop using this module for now.

Curious if there's an update on this?

See #82.

I'm working on using a new precomputed data format which should solve this issue.

Thanks for the update! Will put comments on that PR.

This is fixed in the rewrite and will go out in the 0.1.0 release.
