3256,Extra EOT from NoBuffering mode in emacs,judah,,"Compile the following program:
{{{
import System.IO

main = hSetBuffering stdin NoBuffering >> getLine >>= print
}}}

Then start emacs, run M-x shell, and start the above program.  Paste the output of {{{replicate 252 'x'}}} as input and press return.  An extra EOT character is added to the end of the input:

{{{
$ ./foo
""aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa""     

""\""aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa\""\\
EOT""
}}}

I can make this happen consistently using Ubuntu 8.04.2 and emacs-22.1.1.
I can't reproduce it on OS X or outside of emacs's shell.  

This was originally reported on the Haskeline bug tracker, as it affects ghci/haskeline: http://trac.haskell.org/haskeline/ticket/79 . From that ticket:

> The problem seems to be that Emacs does not send all of the input at
> once:
>   If STRING is more than 500 characters long, it is sent in several
>   bunches. This may happen even for shorter strings.
> (From the documentation of process-send-string in GNU Emacs 23.0.93.1.) See also the following message:  http://thread.gmane.org/gmane.comp.lang.haskell.glasgow.user/15591/focus=15632.
