0.9.4.16:
	"I feel safer already".

	Add a horrible kludge to work around the new Linux kernel
	security features for randomizing memory maps.
	* Before setting up the memory maps, check whether we're running
	  on 2.6 or newer. If so, check where the ADDR_NO_RANDOMIZE
	  personality flag is set. If not, set the flag and re-execute
	  the program.
	* Follow the /proc/self/exe symlink to find out what binary
	  we should be executing. (Can't execute /proc/self/exe
	  directly, since some proc-groveling tools will then show
	  the name of the process as "exe").
	* For more details, see the sbcl-devel threads "Memory randomization
	  problems coming" and "memory randomization patch" in 2005-08.
