A seed that depends only on the ELF

The SNLL threshold becomes thresh in runDEoptim(), so it is part of every cached DEoptim generation's key. Drawing the seed by chance meant a single cache miss on estimateThreshold re-drew the threshold and invalidated every cached generation for that ELF. Keyed on the ELF, a miss costs only the threshold estimate.
