+jam for OWNERS review
+rsleevi FYI (see diff between patch 1 and 2)

Might end up TBRing darin.

Worth noting that a future patch will change weak_ptr.get() back to weak_ptr
when in a boolean context.

btw you should get Darin's ok on this overall change first, since he wrote
WeakPtr and might feel that the current behavior is fine. I looked through the
bug and it didn't seem wrong me.
