[elijahtaylor1, 2014/08/06 00:31:54]

I tried to register an extension registry observer but it didn't get hit.  Is
there an easy way to wait for an install of an extension from the unpacked
installer so I can test this?  I would really like to do as part of this CL

+  // requires either observing extension installs or hooking into the unpacked
+  // installer which is currently not tested in this manner.
+  // const char kIdForPublicKey[] = "ikppjpenhoddphklkpdfdfdabbakkpal";
+}
+
+}  // namespace extensions
