>Environment:
n/a
>Description:
pdksh can become wedged when ^Z is typed while executing a backquote
expression interactively.
>How-To-Repeat:
$ sleep 600 `jot 1000000`
Type ^Z while jot(1) is running. jot(1) will be suspended. ksh will
now ignore ^C. The only way I found to wake it up was to `kill -9'
the jot(1).

None supplied.

Addendum, to document behavior of other shells:
/bin/sh (ours): The ^Z has no apparent effect, and the ^C kills the
jot(1) and goes back to a shell prompt `instantly'.
csh, tcsh, zsh: Similar to /bin/sh, but takes a Long Time to get a
shell prompt again if the jot(1) had output a lot of data. When
linked with the old malloc(3), csh is much faster; I haven't tried
this with the others.
bash: Same problem as pdksh.
