Key cache capacity: 1 when using KeysCached="50%"

[Ran Tavory]

I've noticed that when defining KeysCached="50%" (or KeysCached="100%" and I
didn't test other values with %) then cfstats reports Key cache capacity: 1

This looks weird... is this expected? (version 0.6.1)

For example, in the default configuration:

      <ColumnFamily Name="Super2"
                    ColumnType="Super"
                    CompareWith="UTF8Type"
                    CompareSubcolumnsWith="UTF8Type"
                    RowsCached="10000"
                    KeysCached="50%"/>
