Yes, thanks. I really forgot on this change.
My rough results are now:

            Old s./wc enabled   New s./wc enabled   New s./wc disabled

tar xvfz    8 minutes           4 minutes           14 minutes
rm -r       5 minutes           1 minute            2 minutes

There is another reason for tar "slowness": Current version of
tar seems to be faster than our old system tar: 3m23 against 3m44
for tar xvfz with wc enabled. I think there are even bigger
differences with tar cvfz and tar xvfz with wc disabled.
