	* google-perftools: version 0.95 release
	* Better -- not perfect -- support for linux-ppc (csilvers)
	* Fix race condition in libunwind stacktrace (aruns)
	* Speed up x86 spinlock locking (m3b)
	* Improve heap-checker performance (maxim)
	* Heap checker traverses more ptrs inside heap-alloced objects (maxim)
	* Remove deprecated ProfilerThreadState function (cgd)
	* Update libunwind documentation for statically linked binaries (aruns)
