It limits the amount of memory used for in-transit data, and limits long
running connections to the speed of the client.

Lets imagine a modem user requests a 1GB file. If your READ_AHEAD_GAP is
1GB then Squid will read all the file at full network speed, buffering
it in memory. The end result is that you runs out of both memory and
internet bandwidth.
