This..... dosent work.

jobRebroadcastTimeout does not update correctly the mining difficulty if the mining difficulty in THE SAME BLOCK changes with time.

[ghost]

so if the mining difficulty is adjusted with time, like in some adjusted darkgravitywave algorithm that scale difficulty down with TIME ( for example, progressively lower difficulty if there is a long stale tip..... ) ..... the pool dosent brodcast that info, and the miners keeps trying to mine a higher difficulty block, and if a block is found, the difficulty bits dosent match the pow difficulty bits.

[ghost]

When a new block is found, the pool sends a new getblocktemplate and checks the new difficulty for the next block. jobrebrodcast timeout should also do this.

Or a new option could be added for coins that changes difficulty in the same block over time.

[ghost]

.on('broadcastTimeout', function(){
emitLog('No new blocks for ' + options.jobRebroadcastTimeout + ' seconds - updating transactions & rebroadcasting work');

        GetBlockTemplate(function(error, rpcData, processedBlock){
	 emitLog('This is the value of rpcData : ', rpcdata);
	 emitLog('Its supposed to return if there is an error or a processedBlock ....  will it return ?');
            if (error || processedBlock) return;
	 emitLog('no, did not return...');
            _this.jobManager.updateCurrentJob(rpcData);
	emitLog('sent updateCurrentJob(rpcdata) to jobManager');
        });

Further debugging gives this :

2019-03-09 13:02:32 [Pool] [lightningcash gold] (Thread 5) Its supposed to return if there is an error or a processedBlock .... will it return ?
2019-03-09 13:02:32 [Pool] [lightningcash gold] (Thread 5) no, did not return... ( normal here.... )
2019-03-09 13:02:32 [Pool] [lightningcash gold] (Thread 5) This is the value of result : (empty ???)
