Comment (by gigem):

 Excellent findings, Klaas!  I read somewhere along the lines of container
 traversal being thread safe when done in read-only mode.  Read-only can be
 interpreted different ways besides just using const iterators.

 I agree with your suggestion to switch nearly all of our uses to const
 iterators.  We don't allow deleting map entries and after initialization,
 we only add entries in MainServer::HandleAddChildInput() which uses
 exclusive, write locking, so we should be good.
