      Description

      Testing for DM-10043 has revealed that having maxtasksperchild=1 in the pool initialization for mosaic.py (the pool being used to read input catalogs in parallel) causes a bug where mosaic.py hangs indefinitely. Curiously, this happens only in with the LSST stack (pybind11 version), not with the HSC stack. It has been demonstrated that removing this constraint removes this hanging behavior.
