Bug Description
Twitter has implemented a few changes to mysql and mysqld safe that help prevent imbalanced memory allocation across numa nodes. Implementing these in Percona Server would be a huge win for my company, as we have been having issues with Numa imbalance. We have found that modifying the mysqld_safe to do numactl --interleave all has helped, but has not resolved the issue totally.
Here are the twitter patches that I would like to request be implemented in Percona Server.
