;strategy Small-interval CMP scanner that bombs with a SPL 0 carpet.
;strategy 2.0: smaller
;strategy 2.1: larger, but should tie less; changed scan constants
;strategy 2.2a: smaller
;strategy 2.3a: mutagenizes core
;strategy 2.4: smaller CMP interval, spends less time bombing
;strategy 2.4b: mutagenize constant optimized
