This fix adds Notes.ini variable: FTG_USE_FAST_BINARY_SORT.
Setting this to 1 will use a more efficient binary sort to merge some of the index information.
Not setting the variable or setting it to 0 will use the existing sort.
This has no effect on the creation of new indexes and will only show an improvement where there a large number of keys added to an existing index.
This SPR is fixed in 7.0.2
