…with reCheckTX (backport cometbft#3314) (cometbft#3338) This PR is a combination of ideas from @ValarDragon, @hvanz and @sergio-mena to alleviate nodes that, while not having their mempool full "officially", they have too many TXs lingering in the mempool which causes them to fall behind. The mechanism works as follows: * We mark when we start and end reChecking * If, by the time a new block is decided we are still running the previous `reCheckTx`, we declare the mempool as rechecktx-full * Otherwise, we declare the mempool as not rechecktx-full We have tested this and it fixes the failing nightlies that are blocking us from cutting `v1.0.0-rc1`. Some UTs need to be fixed, hence posting as draft for the moment. --- #### PR checklist - [ ] Tests written/updated - [x] Changelog entry added in `.changelog` (we use [unclog](https://github.com/informalsystems/unclog) to manage our changelog) - [ ] Updated relevant documentation (`docs/` or `spec/`) and code comments - [x] Title follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) spec <hr>This is an automatic backport of pull request cometbft#3314 done by [Mergify](https://mergify.com).
