Hmm, that seems to be a rather slow system.
On my desktop system on ext4 here, it is:
  creating a 400000-entry directory took 6 seconds
  removing a 400000-entry directory took 4 seconds

The test measures the time for the creation, and uses it to verify
that the removal is faster.

Depending on other activities on the system during creation vs. that during
the deletion, the test might fail.

Is it always reproducible on that system, or was this just a one-off?

Have a nice day,
Berny
