Review Comment:
1. I would prefer avoid touching this, as this is pre-existing logic that
I'm just extracting to a separate method, and I would like to minimise changes
for this already pretty fragile bug fix (I've been struggling to fix all of the
failing e2e/itcases for quite some time).
2. This can't loop for more then one or maybe a couple of times. Task can't
keep changing it's state for a long period of time. At worst this will just
make two or three iterations.
