+   with its heap growth in limited address range contexts.  While static linking is still
+   possible, in most environments there will be external shared libraries in the address
+   space, and this is beneficial from a system performance perspective in any case.  GCL
+   goes to significant lengths to detect mmap_base and move it out of the way where possible
+   to allow for maximum contiguous heap growth (e.g. just under 3Gb on 32bit systems at
+   present).  Linking against libX11 at a minimum will call malloc before main via
+   constructors in that library.  Likewise dlopen of GCL's libboot.so will malloc early,
+   but after main.  Such calls as these have no effective cleanup routines available before
+   exit, and furthermore write aslr random data therein foiling reproducibility if saved
+   in the heap.  Such would be useless dead space on reexec if stored there in any case.
+   Traditionally we called gcl_init_alloc here, and this works, but it seems more advisable
+   to ring fence the aslr/shared library world into its own domain and store such mallocs
+   outside the heap in non-reclaimable memory (ie. leaked).  At present leak_malloc is only
+   used for the dlopen of libboot.so which is critical for a reproducible build, but wrapping
+   all dlopen thus may be advisable someday.  Right now the image dumps from raw image
+   runs, and from saved images with GCL_NO_TRUENAME set and in which the run just loads
+   .o files and saves are reproducible, which is sufficient for Debian gcl dependencies:
+   hol88,maxima,acl2,fricas and axiom.  CM 20260625*/
