Do we really need the "fork()"

duplicate the entire volatile memory of the current shell in order to run
another - all we need to do is "run" another shell with the same Env and
local variables, right? We could send the daughter shell a message
containing the current variable settings.
What if the shell uses internal data structure to store state ?
Surely the use of "fork()" is an overkill
for a shell?
No, absoultely not. In fact, shells are one of two cases where fork is
actually not absolutely horrendously braindead (the other is demon
processes).
