NB: these are the same errors as with 8.8.rc2 and, IIRC, as with 8.8.rc1. So it seems the errors are reproducible when doctesting with "make ptest-python3". They are not directly related to parallel doctesting though, since ./sage -tp --long --warn-long 50.3 src/sage/schemes/ yields Running doctests with ID 2019-06-24-13-52-38-4df2b045.
