[issue43885] ResourceWarning: unclosed test_pha_required_nocert

[Christian Heimes]

New submission from Christian Heimes :

bpo-35926 and fb7e7505ed1337bf40fa7b8b68317d1e86675a86 introduced code that is 
triggered resource errors and unhandled exceptions. It has been bothering me 
for a while but I could never pin point the issue. Victor's and Hai's commits 
e80697d687b6 and 73ea54620a6f seem to be related, too.

I don't understand the purpose of the test changes in 
fb7e7505ed1337bf40fa7b8b68317d1e86675a86. The commit looks wrong to me. Could 
you please take a look?
