Open ncftp to a site, login, lls, when you type `lls' it
causes the screen to not echo commands back to you, upon
exiting ncftp the terminal is also the same, requires you to
type `reset' to recover. This is a reproducible problem.
This occurs on both my sparc and intel, probably alpha as
will be fixed in the next kernel and or glibc release.
It's a problem with popen() & vfork().
Workaround: Downgrade to ncftp from Red Hat 5.2 (do rpm --rebuild on
the .srpm first).
