Okay, I profiled your worker code and results can be found here:

http://backgroundrb.gnufied.org/worker_result.html

What this indicates is, worker is spending quite a bit of time inside,
ActiveSupport::Dependencies#new_constants_in, what this means is,
ActiveSupport really screws constant loading in a big way and slows it
down.

I do not have a solution since this is hardly bdrb problem.
