C shell (/bin/csh) profides for ~/.logout.

I think bash also supports a logout script ( .bash.logout or something like that)

Well, the way Linux and Unix work, only ONE copy of the shell executable
is kept in memory....2nd, 3rd, etc processes all reference the same
pages of memory.... so I don't think the memory issue is as big as you
might think it is.

And memory is cheap enough that memory is an issue, buy a bit more,
and solve the headache.
