 * Also look in compiler/x86/parms.lisp for some of the parameters.
 *
 * The memory map for Solaris/x86 looks roughly like
 *
 *	0x08045000->0x08050000   C stack?
 *      0x08050000->             Code + C heap
 *      0x10000000->0x20000000   256 MB read-only space
 *	0x20000000->0x28000000   128M Binding stack growing up.
 *	0x28000000->0x30000000   256M Static Space.
 *      0x30000000->0x31000000   16M Foreign linkage table
 *	0x38000000->0x40000000   128M Control stack growing down.
 *	0x40000000->0xD0000000   2304M Dynamic Space.
 *
 * Starting at 0xd0ce0000 there is some mapped anon memory.  libc
 * seems to start at 0xd0d40000 and other places.  Looks like memory
 * above 0xd0ffe000 or so is not mapped.
