testing: test with child process sometimes hangs on 1.10; -timeout not respected [1.9 backport]

[gopherbot]

@FiloSottile requested issue #24050 to be considered for backport to the next 1.9 minor release.

@gopherbot please open backport tracking issues. This might be a 1.10 regression, or also a 1.9 issue.

@ianlancetaylor which CLs would need to be cherry-picked for this to be fixed? Seems that the original issue isn't.

[ianlancetaylor]

I don't actually know what's going on with that issue. As far as I know it isn't fixed so there is no CL to backport.

[ianlancetaylor]

Closing this issue. The original issue is not fixed. There is no reason to have an issue opened for a backport of an issue that is not fixed.
