Ash + telnetd: telnet client hangs after exit

[Alexander Kriegisch]

Before I test the patch, one more question: Do I always have to user
"-K" to get the desired behaviour? should telnetd not behave like other
implementations? I would rather implement a switch if for people who
like to have a different behaviour.

Beside finding it a bit annoying to set that switch, it would not be a
problem to set it in situations under my control, but as other
applications also start telnetd - why this is so, would lead us too far
astray, so I refrain from explaining the whys, how and wheres - there
are situations beyond my control.

I regard this issue a bug, just because of the unexpected behaviour
which is also different from other telnetds, not because I think your
implementation is bad.
