I'm a bit lost - what does this provide above existing tools - e.g. MallocDebug+Shark on OSX or Valgrind/heap/leaks/etc on Linux?

the shim outputs a log of the memory allocation functions called (malloc,realloc,calloc,free) that can be replayed by the replayer program.

you can then replay the exact same allocation pattern against different allocators to determine which is best for you.

to my knowledge, the tools you mention do not provide similar functionality.

Right ok.... What I don't get is that it mentions profiling the advantage of TCMalloc, which is thread-cached malloc. Is this going to be realistic when the replayer is a single thread? (I could be missing something)
