Yes but running with this patch would allow us to verify that we understand
what is causing the problem. There are other solutions like skipping to the
next partial slab on the list that could fix performance issues that the patch
may cause. A test will give us:

1. Confirmation that the memory use is caused by the trylock.

2. Some performance numbers. If these show a regression then we have some
markers that we can measure other solutions against.
