A while ago, a colleague had a "memory leak" reusing a PB message

was that pb_message::Clear() calls vector<something>::clear() and
string::clear() which does not really release the memory allocated.
I can't really tell for sure actually.
@Kenton, does that make any sense? If yes, is there a way to avoid it?
Yes, I have run into this same issue, when I occasionally read in a
"huge" message. I think this is "by design." As Kenton noted: if you
re-use the message, it never has to free / reallocate memory. See the
"Optimization Tips" in this document:

There is a ::SpaceUsed() method that can be helpful.
