Runner jobs don't follow the pending jobs according to concurrency and thread config

sometimes runner jobs just stop to transcript/transcode. for i.e. there is a list of 257 pending jobs « waiting for parent » but no process is occuring for a long period of time. maybe make the runner job check time shorter and btw it would be nice to add an action like « force to process » on the batch selectbox on the runner jobs list page.

updated: seems to be resolved in 6.3.0
