Avinesh, you mentioned at Yang Xu's v1 [1] that EINTR test is getting timed out
randomly. I also experienced timeouts on aarch64 and ppc64le. v1 had 2 tests
(EINTR and EWOULDBLOCK), you here posted only EINTR. I would expect you would
put here only the other one - EWOULDBLOCK. Or am I missing something?

Kind regards,
Petr
