What effect does it have without -readnow but with say:

	$ gdb gdb
	(gdb) break internal_error
	(gdb) run
	(gdb) maint internal-error
	(gdb) backtrace

which is kind of closer to the typical users:

	$ gdb foo
	(gdb) run
	Segmentation fault
	(gdb) bt
	(gdb) list
	(gdb) print pointer
	$1 = 0
	<bugger>
	(gdb)^D

i.e., very few symbols are really loaded.
