	So my personal feeling (having never used it) is that prelink is a pain
to setup, maintain, get distros running with, fragments the disk etc.
etc. ;-) [ but this is all 2nd hand angst ].

	Well - valgrind / cachegrind - sure. You can get some pretty graphical
pictures with do_lookup_x chewing 1/2 the screen ;-) [ and some after
pictures with it burning way less of the screen ] - and it's all data
access problems; L1 & L2 cache misses all over the shop.

	Regards,

		Michael.
