Workqueues have clean and rich API for all basic operations. The code is usually
easier and better readable. It can be easily tuned for the given purpose.
In many cases, it allows to avoid an extra kernel thread. It helps to stop the
growing number of them. Also there will be less thread-specific

There's cancel_work_sync() to stop the self-requeueing ones.
What happens if queue_work runs while cancel_work_sync is in progress?
