Title: Disable forking with FORK_PER_JOB=false

This allows Resque users to specify an environment variable:

FORK_PER_JOB=false

This disables forking on a job-by-job basis. This should reduce
complexity and eliminate file descriptor management issues that result
from forking on a job-by-job basis.
