tokenbucket 1.1.1

# Token bucket

A simple rate limiting algorithm. See [Wikipedia](http://en.wikipedia.org/wiki/Token_bucket) for a more lengthy discussion of how it works and where it is applicable. In essence, it is a constant rate limiting with temporal pooling. This allows for bursts of activity.

## Memcached sharing

Enables sharing across different processes and servers, useful for rate limiting a shared resource (like a Web API.)

from tokenbucket import SharedTokenBucket

tb = SharedTokenBucket(rate=1.0, maximum=5)

tb.use_memcached_key(‘my_shared_token_bucket’) # or tb.use_memcached_key(‘my_shared_token_bucket’, client=mc)
