  - On Linux and some Un*x variants, allocate memory by first trying sbrk,
    and then switching to mmap if that fails.

 To do:
- - REDIRECT_MALLOC and threads combination is getting closer, but currently
-   usually fails because the DTV (dynamic thread vector) used to access
-   thread-local storage is referenced only from the base of a thread stack,
-   but often allocated through malloc.  The symptom on IA64 is a runaway
-   memset in thread creation, which may cause failures elsewhere.
-   Typically large heap sections end up cleared.
+ - REDIRECT_MALLOC and threads combination should work on more platforms,
+   and needs more testing on Linux.
  - Clone marker inner loop to support arch-dependent prefetching,
    and counting of objects marked for finalization.
  - The USE_MUNMAP code should really use a separate data structure
