+ * TODO: Read this before upstreaming:
+ *
+ * As of Apr 2014 there is a bug regaring function type detection logic in
+ * Free/Open/NetBSD implementations of __cxa_finalize().
+ *
+ * What it is about:
+ * First of all there are two kind of atexit handlers:
+ * 1) void handler(void) - this is the regular type
+ * available for to user via atexit(.) function call.
+ *
+ * 2) void internal_handler(void*) - this is the type
+ * __cxa_atexit() function expects. This handler is used
+ * by C++ compiler to register static destructor calls.
+ * Note that calling this function as the handler of type (1)
+ * results in incorrect this pointer in static d-tors.
+ *
+ * What is wrong with BSD implementations:
+ *
+ * They use dso argument to identify the handler type. The problem
+ * with it is dso is also used to identify the handlers associated
+ * with particular dynamic library and allow __cxa_finalize to call correct
+ * set of functions on dlclose(). And it cannot identify both.
+ *
+ * What is correct way to identify function type?
+ *
+ * Consider this:
+ * 1. __cxa_finalize and __cxa_atexit are part of libc and do not have access to hidden
+ * &__dso_handle.
+ * 2. __cxa_atexit has only 3 arguments: function pointer, function argument, dso.
+ * none of them can be reliably used to pass information about handler type.
+ * 3. following http://www.codesourcery.com/cxx-abi/abi.html#dso-dtor (3.3.5.3 - B)
+ * translation of user atexit -> __cxa_atexit(f, NULL, NULL) results in crashes
+ * on exit() after dlclose() of a library with an atexit() call.
+ *
+ * One way to resolve this is to always call second form of handler, which will
+ * result in storing unused argument in register/stack depending on architecture
+ * and should not present any problems.
+ *
+ * Another way is to make them dso-local in one way or the other.
+ */

+/*
