1. Do a lot of heavy filesystem access / use the system a lot (e.g.
compiling large project as noted in #14451)
2. Notice there are now a lot of "slab area"s.
3. Drop into KDL and see via "slab_meta_chunks -c" that these are almost
entirely free.
In my case there were 162 areas at 8MB each, for a total of some 1.3GB of
memory usage (!!). Looking over the code, I'm not really sure how this
happened; it looks like only 2 free chunks are supposed to be kept in
general?
