[tarantool-patches] [PATCH v1] test: app/socket flaky fails at 1951 line

[Alexander V. Tikhonov]

Found that subtest for lua socket emulation on high
loaded hosts closes the socket channel faster than
write channel on finishes:

wch:put("Fu")
c:send("354 Please type your message\n")
sc:close()

It produces the following fail:

[015] --- app/socket.result	Thu Aug 15 02:55:31 2019
[015] +++ app/socket.reject	Thu Aug 15 02:56:55 2019

Decided to block temporary this check to avoid of testing
failures, due to issue is well known and under investigation.

I would propose to run such tests after all parallel ones instead of
disabling: https://github.com/tarantool/test-run/pull/188

Please, verify whether such approch works good.

Then collect all tests that requires such machinery and mark them as
fragile in one commit.

WBR, Alexander Turenko.
