-// 1) The libunwind library.  This is still in development, and as a
-//    separate library adds a new dependency, but doesn't need a frame
-//    pointer.  It also doesn't call malloc.
-//
-// 2) Our hand-coded stack-unwinder.  This depends on a certain stack
-//    layout, which is used by gcc (and those systems using a
-//    gcc-compatible ABI) on x86 systems, at least since gcc 2.95.
-//    It uses the frame pointer to do its work.
-//
-// 3) The gdb unwinder -- also the one used by the c++ exception code.
-//    It's obviously well-tested, but has a fatal flaw: it can call
-//    malloc() from the unwinder.  This is a problem because we're
-//    trying to use the unwinder to instrument malloc().
-//
-// Note: if you add a new implementation here, make sure it works
-// correctly when GetStackTrace() is called with max_depth == 0.
-// Some code may do that.

-
-	* google-perftools: version 0.90 release
-	* (As the version-number jump hints, this is a major new release:
-	  almost every piece of functionality was rewritten.  I can't do
-	  justice to all the changes, but will concentrate on highlights.)
-	*** USER-VISIBLE CHANGES:
-	* Ability to "release" unused memory added to tcmalloc
-	* Exposed more tweaking knobs via environment variables (see docs)
-	* pprof tries harder to map addresses to functions
-	* tcmalloc_minimal compiles and runs on FreeBSD 6.0 and Solaris 10
-	*** INTERNAL CHANGES:
-	* Much better 64-bit support
-	* Better multiple-processor support (e.g. multicore contention tweaks)
-	* Support for recent kernel ABI changes (e.g. new arg to mremap)
-	* Addition of spinlocks to tcmalloc to reduce contention cost
-	* Speed up tcmalloc by using __thread on systems that support TLS
-	* Total redesign of heap-checker to improve liveness checking
-	* More portable stack-frame analysis -- no more hard-coded constants!
-	* Disentangled heap-profiler code and heap-checker code
-	* Several new unittests to test, e.g., thread-contention costs
-	* Lots of small (but important!) bug fixes: e.g., fixing GetPC on amd64
-	*** KNOWN PROBLEMS:
-	* CPU-profiling may crash on x86_64 (64-bit) systems.  See the README
-	* Profiling/heap-checking may deadlock on x86_64 systems.  See README
