I don't see how this could be avoided unless you define a whole
new i/o model internal to rc just for builtins and the backquote
splitter to use.

It looks like that would involve reinventing the OS inside rc, so it
would lead me to suggest that Unix fork is just broken (i.e., it should
be faster) but this is not a very productive avenue to pursue.

It's a shame when you can't use the Unix style when programming in
Unix. Is it time to move onto something else?
