Could you please help further checks? I'm not sure whether the failures are caused by side-effect of the change or not.

Thank you,

[asvetlov]

Please build python from github master.
Docker image is:

1. Obsolete a little
2. Has stripped test package.

[sakurai-youhei]

@asvetlov Thanks, good to know the recent state of Docker image. Here are outputs from python github master (3.8) and 3.7 branch. The same results are brought; Looks like there are more problems other than #146 when running uvloop with 3.7+.

Oops, this PR seems to be duplicate work with #138...

[pfreixes]

Hi @sakurai-youhei I would say that #138 solves all of the problems and passes all the tests with py37, but waitting the blessing about how to keep moing on from @1st1.
