Change in synchronization I/O.
Reply/response work. Now you basically have to maintain a local copy
of the Job_Observer found in ESL.Job.List. This observer pushes all
BACKGROUND_JOB event packets into a protected list, which then can be
popped by suppling the appropriate UUID.
Patches and changes. More core and call management requests are
implemented, and added lazy parsing to ESL.Reply.Instance's Response.
