Description

We should consider removing support for the --disable_mem_pools feature. It was originally somewhat useful for debugging memory-related issues where memory pooling could limit the effectiveness of ASAN's checks. However, now we use ASAN's poisoning in all cases, which provides most of the same coverage and is used by default with ASAN.

We don't routinely test --disable_mem_pools so we should consider removing it to save the burden of maintaining these extra code paths.
