	* google-perftools: version 0.2 release
	* Use mmap2() instead of mmap(), to map more memory (menage)
	* Do correct pthread-local checking in heap-checker! (maxim)
	* Avoid overflow on 64-bit machines in pprof (sanjay)
	* Add a few more GetPC() functions, including for AMD (csilvers)
	* Better method for overriding pthread functions (menage)
	* (Hacky) fix to avoid overwriting profile files after fork() (csilvers)
	* Crashing bugfix involving dumping heaps on small-stack threads (tudor)
	* Allow library versions with letters at the end (csilvers)
	* Config fixes for systems that don't define PATH_MAX (csilvers)
	* Confix fixes so we no longer need config.h after install (csilvers)
	* Fix to pprof to correctly read very big cpu profiles (csilvers)
	* Fix to pprof to deal with new commandline flags in modern gv's
	* Better error reporting when we can't access /proc/maps (etune)
	* Get rid of the libc-preallocate code (which could crash on some
	  systems); no longer needed with local-threads fix (csilvers)

 HEAP PROFILER
 
-1) Fix heap profiling under STL
+1) Fix heap profiling under all STLs
    * Find out how to force non-glibc STL libraries to call new() and
      delete() for every allocation / deallocation.
    * Make heap profiler ignore STL-internal allocations for those
      libraries under which we cannot profile accurately, so we only
      see object-level leaks.
-2) Remove dependency on tcmalloc
+2) Remove dependency on tcmalloc?
 3) Port to non-linux O/Ses (right now code uses /proc for library info)
 4) Port to non-x86 architectures (locking code in internal_spinlock is
    x86-specific)
 5) Port to C?
+6) Figure out how to get setenv() to work properly before main() in
+   shared libaries, and get rid of the profile-naming hack once we
+   do.  (See HeapProfiler::Init().)

 2) Remove requirement that the heap-checker must be linked last into
    an application (hard! -- it needs its global constructor to run
    first)
+3) Improve heap_checker.html documentation.
 
 TCMALLOC
 
 1) Implement mallinfo/mallopt
 2) Have tcmalloc work correctly when libpthread is not linked in
+   (currently working for glibc, could use other libc's too)
 3) Return memory to the system when requirements drop
 4) Explore coloring allocated objects to avoid cache conflicts
 5) Explore biasing reclamation to larger addresses
