+// 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. |
