Vincent Driessen 1cbf92c166 Workaround for os.waitpid() throwing an OSError on SIGINT. 
When SIGINT (``Ctrl+C``) is received when inside a blocking
os.waitpid(), OSError is thrown, effectively cancelling the wait.

However, to facilitate a "warm shutdown", as we intend, Ctrl+C is
perfectly allowed and we want to keep waiting for the child.  Therefore,
we perform a trick here, catching OSError, checking whether its cause
was SIGINT (errno == EINTR), and only in that case, loop to os.waitpid()
again.

Vincent Driessen e278bd2967 Exit gracefully when user hits Ctrl+C in a worker. 
The currently running task will be waited for, so it can gracefully
be finished.  Further execution will be stopped.

If, during this waiting phase, Ctrl+C is hit again, the worker and the
horse will be terminated forcefully (this means work could be lost or
partially finished).

Vincent Driessen d780c929c0 Change semantics of work(). Add work_burst(). 
work() will now start the worker run loop, and work_burst() now leads to
the burst-then-quit behaviour.

Vincent Driessen a5ea45af57 Make the dequeue methods return values consistent. 
I merely refactored the internal calls. No external API changes have been made in this commit. In order to make the dequeueing methods consistent, each dequeue method now returns a Job instance, which is just a nice lightweight wrapper around the job tuple.

The Job class makes it easier to pass the method call info around, along with some possible meta information, like the queue the job originated from.

This fixes #7.

Vincent Driessen f492a5ae2b Restructure some code. 
No functional change, but leave the BLPOP'ing to the Queue, as the
queues know how to pop themselves.

Vincent Driessen 1a893e60cf Have work() return whether work has been done, or not. 
And promote Worker to the rq namespace, so you can
    from rq import Worker

Vincent Driessen 1c9fa66bc1 Greatly simplify the setup. 
Jobs don't even need to be tagged.  Any function can be put on queues.

Vincent Driessen 8dfdd452ef Bugfix. 
Yeah, it's getting late.

It's my own fault.

I know.

Vincent Driessen 04c88577ed Bugfix: LPOP does not support multiple queue arguments. 
Redis' BLPOP command takes multiple queue arguments, but LPOP can only
take a single queue.  Therefore, we need to loop over all queues
manually, in order, and raise an exception is no more work is available.

Vincent Driessen 518db8c24b Add better connection management. 
To start using RQ, push a Redis connection up its stack, like so:

    from rq import push_connection
    push_connection(Redis())
