-// This tests the accounting done by tcmalloc.  When we allocate and
-// free a small buffer, the number of bytes used by the application
-// before the alloc+free should match the number of bytes used after.
-// However, the internal data structures used by tcmalloc will be
-// quite different -- new spans will have been allocated, etc.  This
-// is, thus, a simple test that we account properly for the internal
-// data structures, so that we report the actual application-used
-// bytes properly.
