  Issue Type: Improvement

Priority: Minor
 Fix For: 1.2.11, 2.0.1

 Attachments: j5980-a.txt


 We have the option {key,row}_cache_keys_to_save so that operators can chose a 
 balance between can't handle load on cold start and takes too long to 
 reboot.  However, this can currently only be set at startup.  This means 
 that once it has been determined that X is a bad value for keys_to_save 
 another badness inducing restart is required to change X.
