           Summary: Konsole does not work as expected when stdout is not
                    buffered in program which run inside it
           Product: konsole
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: omegaminus tochka ru


Version:            (using KDE KDE 3.5.1)
Installed from:    Fedora RPMs
Compiler:          gcc 4.1.0 x86-64 
OS:                Linux

When running some program which unbuffers stdout , konsole shows inappropriate behaviour.
For example:

#!/usr/bin/tclsh
fconfigure stdout -buffering none -blocking false
set i 0
while {1} {
	incr i
	puts -nonewline "$i       \r"
}

This programs executes until Ctrl-C is pressed and displays increasing numbers when run at normal text-mode console.
However, at Konsole it runs for some time and stops randomly at random value of i.
