const TxWaitBlocks = 150

This is the number of THORChain blocks to wait before re-broadcasting a stuck tx with more gas. 150 was chosen because the signing period for outbounds is 300 blocks. After 300 blocks the tx will be re-assigned to a different vault, so we want to try to push the tx through before that
