OK. If the window between now and then is big enough, a __ps_strings
style hack (like the m68k) might be worthwhile. For me, I'd like to
see this in 1.4.2, but I'm realistic.
In other discussion, Jason mentioned getting the `right' start address
for emulations. I wonder how wise that is.
I know AI hackers who paid for high-end commonlisp licenses for Linux;
now they're running their Lisp images on BSD using Linux emulation.
Why? To get a better VM layout for the Lisp heap and stack. This
particular linux app runs better on BSD Linux emulation than on real
Linux. Faithfully emulating the Linux 2Gkva+2Guva VM layout would
break that.
Just a datpoint.
