;;; use. (They want to use this address range even if we try to
;;; reserve it with a call to validate() as the first operation in
;;; main().)
+;;; * For NetBSD 2.0, the following ranges are used by normal
+;;; executables and mmap:
+;;; ** Executables are (by default) loaded at 0x08048000.
+;;; ** The break for the sbcl runtime seems to end around 0x08400000
+;;; We set read only space around 0x20000000, static
+;;; space around 0x30000000, all ending below 0x37fff000
+;;; ** ld.so and other mmap'ed stuff like shared libs start around
+;;; 0x48000000
+;;; We set dynamic space between 0x60000000 and 0x98000000
+;;; ** Bottom of the stack is typically not below 0xb0000000
+;;; FYI, this can be looked at with the "pmap" program, and if you
+;;; set the top-down mmap allocation option in the kernel (not yet
+;;; the default), all bets are totally off!
