      Description

      Recently a few parts of the "Other" time (and actually there are phases outside "Other" that are already parallelized) were parallelized, each using its own gangtask.

      To avoid the constant startup/termination synchronization of the gang threads, try to merge the work into a single (or an appropriate amount of) gangs.

      I added a few CRs that added gang tasks that could be considered for that work.
