- * MALLOC_ZONE_T_NOTE
- *
- * On Darwin, we hook into the memory allocator using a malloc_zone_t struct.
- * We must be very careful around this struct because of different behaviour on
- * different versions of OSX.
- *
- * Each of OSX 10.5, 10.6 and 10.7 use different versions of the struct
- * (with version numbers 3, 6 and 8 respectively). The binary we use on each of
- * these platforms will not necessarily be built using the correct SDK [1].
- * This means we need to statically know the correct struct size to use on all
- * OSX releases, and have a fallback for unknown future versions. The struct
- * sizes defined in osx_zone_types.h.
- *
- * For OSX 10.8 and later, we may expect the malloc_zone_t struct to change
- * again, and need to dynamically account for this. By simply leaving
- * malloc_zone_t alone, we don't quite deal with the problem, because there
- * remain calls to jemalloc through the mozalloc interface. We check this
- * dynamically on each allocation, using the CHECK_DARWIN macro and
- * osx_use_jemalloc.
- *
- *
- * [1] Mozilla is built as a universal binary on Mac, supporting i386 and
- *     x86_64. The i386 target is built using the 10.5 SDK, even if it runs on
- *     10.6. The x86_64 target is built using the 10.6 SDK, even if it runs on
- *     10.7 or later, or 10.5.
- *
- * FIXME:
- *   When later versions of OSX come out (10.8 and up), we need to check their
- *   malloc_zone_t versions. If they're greater than 8, we need a new version
- *   of malloc_zone_t adapted into osx_zone_types.h.
