buffer

This package provides a circular buffer implementation backed by an MMAP'd file. It's purpose is to provide a simple interface for storing arbitrary records backed by a file which can handle failures and is suitable for concurrent access.

Specifically, this is a fork of ashishgandhi's buffer implementation which suits our needs more effectively. Namely, insertions into a full buffer do not overwrite existing records. Instead an error is returned to the caller forcing a decision on how to handle.
