i haven't read most of this note, (still catching up on my mail), but

> any idea why the es executable is so large?

it shrinks in size dramatically if you turn off assertions.  some of the
things that have to be done for the garbage collector generate a lot of
assertions which should really just be compile-time checks.

the other thing is that es has lots of functionality (taken generally
out of the shared libraries, with only a little bit of glue code) that
rc does not have, even if it is minor:  ~-expansion, builtin time(), etc.
a lot of this can be thought of as code bloat.  nevertheless, es w/o
assertions should be roughly the size of a csh linked in the same way.

thanks for your analysis.

paul
