calling `batchMap` + `submitJob` in a loop triggers "Registry must be empty" error

[MLopez-Ibanez]

I would like to call batchMap + submitJobs in a loop to send a bunch of jobs to the cluster. Then, wait for everything to finish. However, I trigger this error:

Is this simply not possible?

OK, this seems to be more or less the same as issue #209 and the suggested work-around seems to be to create a new registry every time, which is not great.
