More bike-shedding: I actually don't get Sean's suggestion to rename
this to split_lock_ac [1]. If split lock detection is able to trigger
some other form of fault/trap we just change the implementation to cope,
we would not want to change the command line argument that enables it,
so split_lock_detect is more informative?

And if the concern is the earlier one [2], then surely everything should
be renamed sld -> slac?
