re: eval and &. Well, input for eval is rescanned noninteractively,
so interactive features get lost during an eval. This is perhaps
bogomorphic. At the same time, however, you don't want rc to print
prompts while it chugs through an eval.

re: wait(). rc does not trap SIGCLD, so it cannot notify you
asynchronously of a child's death. This may be another bogomorphism,
but so far I've been using Occam's razor, i.e., avoiding complexity
in the design whenever possible.
