Read Block Thread
From EMule Wiki
Read Block Thread is a feature origins form the Morph Mod and adopted by many other mods, it moves Block reading operations to a separated thread what increases the performances on fast Lines, and reduces GUI lock downs. There are 2 different implementations the original one from Morph that provides one reading thread for each client and a new one from Neo that provides one reading thread per file, the modification was needed for voodoo.
