-// By default, SQLite tracks the size of all its heap blocks by adding an extra
-// 8 bytes at the start of the block to hold the size.  Unfortunately, this
-// causes a lot of 2^N-sized allocations to be rounded up by jemalloc
-// allocator, wasting memory.  For example, a request for 1024 bytes has 8
-// bytes added, becoming a request for 1032 bytes, and jemalloc rounds this up
-// to 2048 bytes, wasting 1012 bytes.  (See bug 676189 for more details.)
-//
-// So we register jemalloc as the malloc implementation, which avoids this
-// 8-byte overhead, and thus a lot of waste.  This requires us to provide a
-// function, sqliteMemRoundup(), which computes the actual size that will be
-// allocated for a given request.  SQLite uses this function before all
-// allocations, and may be able to use any excess bytes caused by the rounding.
-//
-// Note: the wrappers for malloc, realloc and moz_malloc_usable_size are
-// necessary because the sqlite_mem_methods type signatures differ slightly
-// from the standard ones -- they use int instead of size_t.  But we don't need
-// a wrapper for free.

-// sqlite does its own memory accounting, and we use its numbers in our memory

-// output as unreported, so we mark them as reported when they're allocated and
-// mark them as unreported when they are freed.
-//
-// In other words, we are marking all sqlite heap blocks as reported even
-// though we're not reporting them ourselves.  Instead we're trusting that
-// sqlite is fully and correctly accounting for all of its heap blocks via its
-// own memory accounting.  Well, we don't have to trust it entirely, because
-// it's easy to keep track (while doing this DMD-specific marking) of exactly
-// how much memory SQLite is using.  And we can compare that against what
-// SQLite reports it is using.
