Here are the numbers; there is a spectacular improvement, but 4.3 is still an
order of magnitude slower than 4.2:
With df_hack3 alone:
real 1m5.705s
user 1m5.184s
sys 0m0.412s
With df_double_queue_worklist alone:
real 4m8.383s
user 4m6.055s
sys 0m0.636s
With df_hack3 and df_double_queue_worklist:
real 1m6.834s
user 1m6.024s
sys 0m0.376s
With df_hack2 and df_hack3:
real 0m54.194s
user 0m53.511s
sys 0m0.324s
With df_hack2, df_hack3 and df_double_queue_worklist:
real 0m54.132s
user 0m53.691s
sys 0m0.372s
