* The purpose of these structs is described in jemalloc.c, in the comment
* marked MALLOC_ZONE_T_NOTE.
*
* We need access to some structs that come with a specific version of OSX
* but can't copy them here because of licensing restrictions (see bug
* 603655). The structs below are equivalent in that they'll always be
* compiled to the same representation on all platforms.
*
* `void*` and `void (*)()` may not be the same size on weird platforms, but
* the size of a function pointer shouldn't vary according to its parameters
* or return type.
*
* Apple's version of these structures, complete with member names and
* comments, is available online at
*
* http://www.opensource.apple.com/source/Libc/Libc-763.12/include/malloc/malloc.h
