The problem is that in the OpenBuildService (the build system of SUSE
distributions) /dev/shm is limited to:
abuild@milic:~/rpmbuild/BUILD/Python-3.8.0rc1> ls -ld /dev/shm
drwxr-xr-x 1 root root 0 Oct 5 13:23 /dev/shm
abuild@milic:~/rpmbuild/BUILD/Python-3.8.0rc1>
Provided PR will skip test if /dev/shm doesn’t exist or it doesn’t sufficient
permissions.
