Description
If you spawn say 30 cron processes, each process tries to grab a runner lock and waits a second for each before moving on to the next. This means that the 30th process will sit there for at least 30 seconds doing essentially nothing. The more processes the worse it gets, which make it hard to tune for lots of short lived processes.
