You can reproduce these fails with ORWT if you run tests in same order 
(first the http tests)and without restarting DumpRenderTree.

I managed to reproduce the fails on r92952 with the following command:
$ Tools/Scripts/old-run-webkit-tests --nthly=50000 --wait-for-httpd `cat tests_run0.txt`

I attached the tests_run0.txt generated by NRWT.

It means it isn't an NRWT bug, but a crazy DRT sideeffect bug again ...

Ooops, r- because of bad comment. It is absolutely unrelated to r99402.

It is better, but we need one more round.

I think these entries would be better:

# [Qt] http/tests/notifications/icon-does-not-exist.html makes fast/notifications/notifications-click-event.html fail
# https://bugs.webkit.org/show_bug.cgi?id=71693
http/tests/notifications/icon-does-not-exist.html

# [Qt] http/tests/xmlhttprequest/workers/abort-exception-assert.html makes 6 fast/workers test fail
# https://bugs.webkit.org/show_bug.cgi?id=71695
http/tests/xmlhttprequest/workers/abort-exception-assert.html

Landed in r106001 - awaiting your findings.

I think flakey tests aren't related to NRWT, but the order of test running.
All of them should have own bug reports, so I think we can close this one.
