Nope, that commit should do it.

What version of the client software are you running? I'll have to look
over the change logs to see if maybe there are changes in there that
would impact this as well. Also my test environment is smaller than
yours; I'll endeavor to look this over again on a larger one with more
clients and see if I can spot any extra interactions causing problems.
