+// Todo:
+//
+// - Use a Massif-style allocation tree for unreported blocks -- makes it more
+// obvious if lots of small almost-the-same records add up to significant
+// amounts, and saves the hassle of trying different --num-callers values.
+// Compute it from the stack traces only at CHECK_REPORTING time. Should be
+// able to avoid looking up the debug info until the very end?
+//
+// - Would be good to track mmap'd blocks in such a way that any breakage
+// (e.g. regexp-code wasn't working for a while) is detected. Probably
+// would need suppressions for the common cases like dl_load and pthread
+// stacks.
+//
+// - Insert a sanity-check that REPORT isn't called outside of a
+// CHECK_REPORTING context (need to mark the end of such a context). [Would
+// need to distinguish between traverse-REPORT and counter-REPORT].
+//
+// - Probably should split DMDV_REPORT into two, one for each kind of reporter,
+// and store maintain-a-counter counts in a separate table.
+//
+
+// A note about reporter styles:
+// - Traverse-based reporters are easy to handle. They just call DMDV_REPORT
+// on each heap block. If we only had that style of reporter then all R
+// bits would be clear before about:memory is loaded, and we could clear all
+// R bits after CHECK_REPORTING is finished.
+//
+// - Counter-based reporters are more difficult. We could suppress
+// them, but that's inaccurate -- e.g. we could be missing some slop bytes
+// and not know. It's better to call DMDV_REPORT and DMDV_UNREPORT on the
+// relevant heap blocks as they are counted/uncounted. But that means that
+// some hb->isReported flags are set even before about:memory is loaded;
+// and those bits should still be set afterwards. Could introduce a second
+// flag to handle this, but for now we just restrict CHECK_REPORTING to only
+// be called once.
+
+// A note about terminology:
+// - A block that isn't fully reported is "under-reported". (But all heap
+// blocks are now either fully-reported or not reported at all.)
+// - Bytes within that block that aren't reported are "unreported".
+// - So "under-reported" refers to blocks, "unreported" refers to bytes.
