A small change to accelerate the building of the affyid index - usually the last phase of the incremental loader. On dev (as of today) this should take the time down from ~2 hours to ~20 minutes. The limiting step is the disks (reading the whole icd array) - adding faster disks (read speed), or more nodes will speed it up more. This whole path may be unnecessary if new affyids are not added during load.

Manny reached out yesterday saying loads into dev were slow. This change (two commits go together) should speed up one of the last-phase queries.
For more speedup - consider switching to faster disk drives or adding more nodes - this process is bottlenecked on disk read.
