I meant specifically for package methods under Unix (that file
Makefile.in).  There is in principle no need to save the image prior to 
preparing the lazyloading database but that needs code changes for 
methods.

The standard packages either use lazy loading (most) or not (the small 
ones, splines and tcltk) without any choice.  (There was a choice under 
Unix for a short while.)

For all contributed (including recommended) packages, lazy loading can be 
controlled by INSTALL --lazy/--no-lazy unless the package itself insists
via its DESCRIPTION file.  If unspecified, INSTALL selects lazy loading 
for largish packages without saved images (about 27% of those on CRAN 
yesterday).
