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
