> It was discovered that the ClientMetadataService would call into CacheImpl, which contains a backreference to Cache, and this could occur in the middle of a Cache move, where the pimpl pointer was updated, but not the backreference.
> The solution will be to guard the pimpl during the move, so the Cache can update it's pimpl and the backreference. There exists CacheImpl::doIfDestroyNotPending that locks the pimpl while executing a function to facilitate this.
