* To get the gap list we will process analog

		   This meant that on average 90k was lost for every connection
		   to a client data source. That is a lot of wasted data.

		   To reduce the lost data, packets are now written to a buffer
		   and flushed to disk regularly regardless of size downloaded.
		   This includes compressed packets.

		   Data is also requested only where gaps are, not in 180k blocks.
		   The requests will still not exceed 180k, but may be smaller to
		   fill a gap.

	// download. To avoid a prematurely stop of the downloading, all blocks that 
	// are requested from the same source must be located within the same 
	// chunk (=> part ~9MB).
	//  
	// The selection of the chunk to download is one of the CRITICAL parts of the 
	// edonkey network. The selection algorithm must insure the best spreading
	// of files.
	//  
	// The selection is based on several criteria:
	//  -   Frequency of the chunk (availability), very rare chunks must be downloaded 
	//      as quickly as possible to become a new available source.
	//  -   Parts used for preview (first + last chunk), preview or check a 
	//      file (e.g. movie, mp3)
	//  -   Completion (shortest-to-complete), partially retrieved chunks should be 
	//      completed before starting to download other one.
	//  
	// The frequency criterion defines several zones: very rare, rare, almost rare,
	// and common. Inside each zone, the criteria have a specific ‘weight’, used 
	// to calculate the priority of chunks. The chunk(s) with the highest 
	// priority (highest=0, lowest=0xffff) is/are selected first.
	//  
	// This algorithm usually selects first the rarest chunk(s). However, partially
	// complete chunk(s) that is/are close to completion may overtake the priority 
	// (priority inversion). For common chunks, it also tries to put the transferring
    // clients on the same chunk, to complete it sooner.
