33 // We expose the TCMallocGuard class -- which initializes the tcmalloc
34 // allocator -- so classes that need to be sure tcmalloc is loaded
35 // before they do stuff -- notably heap-profiler -- can. To use this
36 // create a static TCMallocGuard instance at the top of a file where
37 // you need tcmalloc to be initialized before global constructors run.
