         just use a global variable or something similar if it's easier for you particular situation. The quit job
         remains in the queue and will continue to be returned by future calls to ma_resource_manager_next_job(). The
         reason for this is to give every job thread visibility to the quit job so they have a chance to exit.

+        We won't actually be hitting this code because the call above will return MA_CANCELLED when the MA_JOB_QUIT

+        return value of ma_resource_manager_next_job() you will want to check for MA_JOB_QUIT like the code below.
