*That* happens even if I never enter grub at all -- so I guess you would 
say "before".  GRUB doesn't have that problem for me as far as I know, 
but the only things I have in my config are (hd0,x) -- no boot-from-CD 
option, only the Linuxes on the disk that I have configured precisely 
and numerically.

look, here is my boot sequence:
EFI firmware boots the MacOSX partition by default, if I don't hold down 
"option"/"alt" (if I do, then the firmware puts up a menu of choices).

rEFIt is installed in such a way that it is booted rather the standard 
MacOSX at that point.  It puts up a nice menu of choices including 
MacOS, any bootable CD/DVDs, and all the GRUBs it can find.  It's 
rEFIt's appearance that is delayed when there's a CD in the drive. 
rEFIt knows how to boot both EFI and BIOS GRUBs.
-- MacOSX: boots normally if selected in rEFIt.
-- GRUB2: well, you know about that.  From there, I can potentially boot 
my Linuxes that are on various of my partitions.
