Regular signet reorgs

The programmer discusses a strategy to manage blockchain reorganizations by setting conditions that only trigger a reorg if the previous block is at least 25 minutes old. This approach leverages the timing tactics of the signet miner to enhance the likelihood that the reorg block will immediately become part of the more-work chain. In scenarios where this does not occur as expected, there's a mechanism in place for the miner to reassess the original block and its subsequent blocks shortly after, thus maintaining alignment with the network consensus.

Additionally, there are observed issues where transactions are expelled from the mempool of the programmer's node during these reorganizations but remain in other nodes' mempools. This discrepancy results in delayed transaction mining until the transactions are manually processed using "sendrawtransaction." The complications extend to transactions within active wallets on the mining nodes, though the underlying reasons for this behavior are unclear. Moreover, the described problems might be influencing the estimation of transaction fees, as detailed in an ongoing discussion in a GitHub issue. This indicates potential broader impacts on network performance and reliability.
