   Just out of curiosity; why 0xE0000000 instead of 0x0?  Would this
   break if it was on a sun4m?

   [ ... ]

   How hard would it be to change the VM such that on a SPARC, if it was passed
   an address in the VM hole - but without MAP_FIXED set - the code would just
   either grab any old address (e.g., like as if 0x0 was passed as the address)
   or use this Mysterious 0xE0000000 Magic Address that's not in the hole?

Nothing mysterious about 0xe0000000, its the first valid user vm
address after the sun4c address space hole.
