[Backgroundrb-devel] Rails after_initialize block doesn't seem to be run in the backgroundrb context

Nick,

I am convinced at this point that it's time to move on to Delayed Job. For one thing, Engine Yard strongly discourages the use of backgroundrb, and will not allow it at all on their cloud servers. I have made a great deal of effort to have as little code as possible in the workers already (good design practice to put business work in models - backgroundrb is an implementation detail), so making the migration should be relatively easy.

There are some strange behaviors in backgroundrb, like this, that make it quite frustrating (for instance, how in the world does one make the logging work??). Coupled with the lack of current development (understandable), it seems to make sense to move on to more supported/encouraged technology.

I know that doesn't help, but just in case you were considering the move already :)
