acquia_purge 7.x-1.0-alpha2

Second alpha release that is a continuation of the earlier adoption of Drupal's queuing API but with further - yet experimental - changes in the underlying HTTP processing to ensure better stability when used in combination with many balancers, domains or just many purges.

Some of the important changes include:

• Drastic reduce of the burden put on the queue API and lowered item payload.
• Dynamic calculation of resources and how many HTTP requests can be done per step.
• Parallel issuing of HTTP requests, 6 at a time. Drastically speeds up purging.
• Low-level preparation for HTTPS support, not usable yet but paves the path for support.
• Drush ap-forget has been reimplemented and is now much, much faster, works under high queue loads.
• Behavior change: copying your database across environments now means that purges continue, even if they have wrong URLs. Use "drush apf" to clear the queue.
• API change: acquia_purge_purge_path() and ..paths NO LONGER take $domains as second parameter, this in order to simplify API usage and better separation of concerns.

Everybody is encouraged to put this version to the test and to inform me of any issues, instabilities or other types of feedback. With the important added note that it hasn't been tested widely yet.
