Comment # 8 on bug 1080251 from Timo Jyrinki

I'm unable to reproduce the bug on SLE12 here when trying to see if it's fit
for release:

# time ./a.out 

real    0m12.521s
user    0m12.002s
sys    0m0.504s
# 

I've done multiple retries.

# cat /etc/os-release
NAME="SLES"
VERSION="12-SP3"
VERSION_ID="12.3"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
...

The patch itself seems fairly straightforward mutex adding, but I'm unsure at
the moment if to accepting it if there's no reproducable bug it's fixing on
SLE12. The CVE that was fixed in openSUSE in the same go has already been fixed
in SLE12.
