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