ACK.  We've had patches like this in the past (commit 054d43f came to my 
mind).

It might be nicer to someday refactor the code to move the burden into 
the begin-job helper, instead of repeating it on all callers, but as 
that is a bigger patch, and would cause more merge conflicts across 
backports, I'm okay if it gets delayed until someone really has the time 
and motivation to tackle that project.
