>Description:
If I type a while loop into sh, then try to ^C or ^Z out, the shell
refuses to go away.  FWIW, the session below is being run in a telnet
window from a Mac, using tcsh as the login shell, but folks on other
systems have replicated the problem.  The bug is present in both
FreeBSD 2.2.8 and 3.2.
>How-To-Repeat:
  % sh
  $ while :; do
  > echo foo
  > sleep 60
  > done
  foo

  [Interrupt Process]		<- ^C hit

  [Interrupt Process]		<- ^C hit

  ^Z%1 Suspended		<- ^Z hit
  foo

  ^Z%2 Suspended		<- ^Z hit
  foo
