BTW (unrelated to this commit, as it was not added to this commit) tst_brk()
definition from include/tst_test.h contains also
TST_BRK_SUPPORTS_ONLY_TCONF_TBROK().
And tst_res() has also TST_RES_SUPPORTS_TCONF_TFAIL_TINFO_TPASS_TWARN().
We could rename tst_res_flags.h to tst_res.h and add there tst_brk() and
tst_res() definitions and tst_brk_() and tst_res_() signatures.

Interesting there is no any usleep().
Kind regards,
