/* Define compression parameters for IPC messages

 * Compression costs a LOT, so we don't want to do it unless we're hitting
 * message limits. Currently, we use 128KB as the threshold, because higher
 * values don't play well with the heartbeat stack. With an earlier limit of
 * 10KB, compressing 184 of 1071 messages accounted for 23% of the total CPU
 * used by the cib.
