> ATM we scan each data directory four times. We could easily reduce that to at
> least two, maybe to one.
> 1. pre-flight (startup tests) scrub
> 1. pre-flight (startup tests) sstable min version
> 1. {{ColumnFamilyStore.createColumnFamilyStore}}
> 1. {{ColumnFamilyStore.<init>}} (if {{loadSSTables==true}})
> First two pre-flight tests could be combined to one and 3+4 could also be
> combined, as both appear at pretty related code paths.
