Remove CPAN Dependencies, Stability Improvements

Removed dependency on CPAN packages for multi-threaded operation. While it might not be a bad idea to update the `threads` and `Thread::Queue` packages, it is no longer necessary.

Modified wait backoff to use a Fibonacci rather than geometric sequence. This will make wait time grow less aggressively while still giving reasonable values.

Added vagrant test configurations for Ubuntu 12.04 and CentOS 6.

More options for regression tests and improved code to run in a variety of environments.
