[jochen (gone - plz use gerrit), 2014/02/24 11:21:52]

instead of putting this into gin/, i'd put it into
content/shell/renderer/test_runner to discourage use outside of it.

Done. (I put this into the namespace 'content', but it might be better to put
UnsafePersistent into the other namespace, like WebTestRunner).

 // memory pointed by it is not going away: 1) When GC cannot happen while the
 // UnsafePersistent is alive or 2) when there is a strong Persistent keeping the
 // memory alive while the UnsafePersistent is alive.
