That really shouldn't happen ... are you sure you did a full recompile
after changing NUM_LOCK_PARTITIONS?

Actually ... wait a moment.  The default value of NUM_LOCK_PARTITIONS
is already 16 (1 << LOG2_NUM_LOCK_PARTITIONS where the latter is 4).
Are you saying you set LOG2_NUM_LOCK_PARTITIONS to 16?  That would be
way too many partitions.  I was thinking of testing
LOG2_NUM_LOCK_PARTITIONS in the range of about 2 to 5.
