	I just had an interresting thought.  There is such a thing
as a dis-assembler, but is it possible to write an un-loader.  In
other words, I'd like to have a tool were I can break up an executable
into the object files that it was loaded with, i.e. un-load it.  With
such a tool, a computer sight with only executables can un-load a
program and then re-load it with there own version of a subroutine.
As an example, the recent time change hack.  I could have taken
executables I no-longer have the source to and loaded in the new ctime
functions.

	Just so you know, we have many VAXes plus pdp-11 like
computers running BSD4.? and ULTRIX 1.2, 2.0 and our own BBN OS UNIX 
with sources to everything.
