OK, either tape sort is broken or trace_sort is. The larger my
maint_work_mem, the MORE tapes it wants to use:
LOG: begin index sort: unique = f, workMem = 4194304, randomAccess = f
LOG: switching to external sort with 14980 tapes: CPU 33.33s/24.23u sec
elapsed 58.86 sec
LOG: begin index sort: unique = f, workMem = 131072, randomAccess = f
LOG: switching to external sort with 469 tapes: CPU 1.87s/1.48u sec
elapsed 3.47 sec
