* 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
