Most tests are not doing it and just call tst_rmdir() in cleanup.
When a testfails in the middle, e.g. with tst_brkm(TFAIL,...),
it will getworthlessTWARN along with TFAIL.

Some tests closes fds in cleanup, and it means that they set global vars
to keep track of open files. I think, itcomplicates a little bit writing
and reading such tests.So that is why I think it's better to have such
cleanup operations insidethe library.

Thanks,
Alexey
