My suggestion is to go ahead and commit this PR with Jyothsna's change to
disable the "graceful" part of the graceful shutdown. The feature will be in
the product and people can turn it on to play with it. Then, @dvjyothsna should
file a JIRA for the improvements we discussed (enabling by default for true
servers, disabling for embedded.)---
