dialog is interactive.  Sometimes it's possible to start dialog (or
other interactive process) and disconnect the terminal input.  Then
(depending on how errors are handled), it tries repeatedly to read

(that's addressed in the version of dialog which I maintain, but FreeBSD
has, iirc, a variant from long ago which isn't strictly compatible).
