    Description

      This is for the internal bug CONFDEV-15413 since I noticed there was no public one tracking this issue.

      Summary

      A page with many watchers will thrash a system's performance by processing/reprocessing mail content for the hundreds of watchers:

      "http-8090-137" daemon prio=10 tid=0x00007fa3bb7c2800 nid=0xf5fd runnable [0x0000000045914000]
