-/* Resource Freeing Hooks:
-
-   Normally a process exits and the OS cleans up any allocated
-   memory.  However, when tooling like mtrace or valgrind is monitoring
-   the process we need to free all resources that are part of the
-   process in order to provide the consistency required to track
-   memory leaks.
-
-   A single public API exists and is __libc_freeres(), and this is used
-   by applications like valgrind to freee resouces.
-
-   There are 3 cases:
-
-   (a) __libc_freeres
-
-	In this case all you need to do is define the freeing routine:
-
-	foo.c:
-	libfoo_freeres_fn (foo_freeres)
-	{
-	  complex_free (mem);
-	}
-
-	This ensures the function is called at the right point to free
-	resources.
-
-   (b) __libc_freeres_ptr
-
-	The framework for (a) iterates over the list of pointers-to-free
-	in (b) and frees them.
-
-	foo.c:
-	libc_freeres_ptr (static char *foo_buffer);
-
-	Freeing these resources alaways happens last and is equivalent
-	to registering a function that does 'free (foo_buffer)'.
-
-   (c) Explicit lists of free routines to call or objects to free.
-
-	It is the intended goal to remove (a) and (b) which have some
-	non-determinism based on link order, and instead use explicit
-	lists of functions and frees to resolve cleanup ordering issues
-	and make it easy to debug and maintain.
-
-	As of today the following subsystems use (c):
-
-	Per-thread cleanup:
-	* malloc/thread-freeres.c
-
-	libdl cleanup:
-	* dlfcn/dlfreeres.c
-
-	libpthread cleanup:
-	* nptl/nptlfreeres.c
-
-	So if you need any shutdown routines to run you should add them
-	directly to the appropriate subsystem's shutdown list.  */
