Ping?

Without this patch the NameConflictDirWalk can get into some serious
trouble, trouble which can cause Gerrit Code Review to have its
memory explode to >8 GiB, because NCDW gets stuck in an infinite
loop, forever allocating reachable memory inside of a MergeStrategy.

I've made a private build of this and am running it in production
within day-job employer, but I can't make a release of Gerrit until
I have a stable identifier for this patch.
