It's not clear from the documentation either
(http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14237/ini
tparams047.htm):
"Note that if the number of sessions is extremely large the multiblock
read count value is decreased to avoid the buffer cache getting flooded
with too many table scan buffers."
