Get estimation for the number of processed entries and bytes read at time t, based on the numbers already processed and the latests worker measured speeds.

If t <= 0 the current time is used. Only the estimation for the entries is currently implemented. This is needed to smooth the instantaneous rate plot.

Get next packet; A meaningfull difference to TPacketizer is the fact that this packetizer, for each worker, tries to predict whether the worker will finish processing it's local files before the end of the query.

If yes, it allocates, to those workers, files from non-slave filenodes or from slaves that are overloaded. The check is done every time a new file needs to be assigned.

This method can be called at any time during processing as an effect of handling kPROOF_STOPPROCESS If the output list from this worker is going to be sent back to the master, the 'status' includes the number of entries processed by the slave.

From this we calculate the remaining part of the packet. 0 indicates that the results from that worker were lost completely. Assume that the filenodes for which we have a TFileNode object are still up and running.
