-;;;
-;;; CMU CL 18b used this nontrivially by default (setting it to 10)
-;;; but consequently suffered from the inability to execute some
-;;; troublesome constructs correctly, e.g. inability to load a fasl
-;;; file compiled from the source file
-;;; (defpackage "FOO" (:use "CL"))
-;;; (print 'foo::bar)
-;;; because it would dump data-setup fops (including a FOP-PACKAGE for
-;;; "FOO") for the second form before dumping the the code in the
-;;; first form, or the fop to execute the code in the first form. By
-;;; setting this value to 0 by default, we avoid this badness. This
-;;; increases the number of toplevel form functions, and so increases
-;;; the size of object files.
-;;;
-;;; The variable is still supported because when we are compiling the
-;;; SBCL system itself, which is known not contain any troublesome
-;;; constructs, we can set it to a nonzero value, which reduces the
-;;; number of toplevel form objects, reducing the peak memory usage in
-;;; GENESIS, which is desirable, since at least for SBCL version
-;;; 0.6.7, this is the high water mark for memory usage during system
