Comment 112 for bug 1672297

This bug is fixed in Ubuntu 18.10, but beware 18.10 also brings a new separate leak: bug 1800165.

This bug is not yet fixed in Ubuntu 18.04 because the fix for this one also causes a performance regression in 18.10 that we don't want to repeat in 18.04:

We will need to backport that fix as part of the fix here so the performance regression is never seen in 18.04. However, technically we are required to get the performance fix into 18.10 before we can proceed with 18.04 here. :S
