	* Decrease fragmentation in tcmalloc (lefevere)
	* Support for ARM in some of the thread-specific code (markus)
	* Turn off heap-checker for statically-linked binaries, which
	  cause error leak reports now (etune)
	* Many pprof improvements, including a command-line interface (jeff)
	* CPU profiling now automatically affects all threads in linux 2.6.
	  (Kernel bugs break CPU profiling and threads in linux 2.4 a bit.)
	  ProfilerEnable() and ProfilerDisable() are deprecated.  (sanjay)
	* tcmalloc now correctly intercepts memalign (m3b, maxim)
	* Syntax fix: added missing va_end()s.  Helps non-gcc compiling (etune)
	* Fixed a few coredumper bugs: race condition after PTRACE_DETACH,
	  ignore non-aligned stackframe pointers (markus, menage)
	* 64-bit cleanup, especially for spinlock code (etune) and mmap (sanjay)
	* Better support for finding threads in linux (markus)
	* tcmalloc now tracks those stack traces that allocate memory (sanjay)
	* Work around a weird setspecific problem (sanjay)
	* Fix tcmalloc overflow problems when an alloc is close to 2G/4G (sanjay)
