Priority for threads

[MatsGard]

I think it would be nice to be able to set the priority for threads just like you can do for processes.
It is possible using "thr.priority= integer", like below.

The value of the integer is however different compared to process, so therefore it might be better to use something else than the :nice option.

Regards Mats

def thread_it(options)
  # clean up stale connections from previous threads
  ActiveRecord::Base.verify_active_connections!()
  thr = Thread.new do
    # run the long-running code block
    yield
  end
  thr.priority = options[:nice] if options[:nice]
  return SpawnId.new(:thread, thr)
end

I'll look into that when I have time... thanks for the suggestion.

Mats, I set the thread priority like this:

    thr.priority = -options[:nice] if options[:nice]

I used the negative value of 'nice' since we want nice processes to have lower priority. It's on the edge branch if you want to try it out.
