    Description

      I've seen some users, always on cloud platforms, say that they have problems with hosts flapping in the FD. GC is not the cause. I know of at least one production deployment where they are already hacking phi to 10 to get around the flapping problems.

      This is a dangerous thing to expose, however, since giving meaning to the difference of 8 and 10 here is hard to quantify to someone unfamiliar with the inner workings. Perhaps we can allow setting it in the config, but not specify a default and leave it commented out with a big fat warning.
