+Subject: [PATCH] Remove <iostream> from the common.h header
+
+<iostream> embeds a global constructor (to initialize std::cout and
+such), typically `static ios_base::Init __ioinit;` in libstdc++).
+
+This header is not directly necessary in the common header and has a
+small impact on every compilation unit that includes it.
+
+As an example, removing that header dependency in turns suppresses 33 global
+constructors from the firefox core library libxul.
