HEAP PROFILER
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?
3) Port to non-linux O/Ses (right now code uses /proc for library info)
4) Port to non-x86 architectures (locking code in 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().)
HEAP CHECKER
1) Remove requirement that the heap-checker must be linked last into
an application (hard! -- it needs its global constructor to run
first)
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
6) Add contention stats to a synchronization.cc (can do spinlocks,
but threads? -- may have to provide our own thread implementation)
CPU PROFILER
1) 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 Profiler::GetUniquePathFromEnv().)
2) Resolve crashing problems on x86_64 (see README)
STACKTRACE
1) Remove dependency on linux/x86
