I had the same problem as you. Somehow it has to do with the use of the
clipboard of KDE... I worked around the problem by marking any text in a
output view with the mouse. Anyhow it clears the clipboard and prevents an
overflow. Usually, the heavy CPU load happened when debugging with the
internal debugger. That time John suspected wrong data exchange between gdb
and kdevelop but we never found out the exact reason for this bug...
Anyway, I committed John's idea for fixing the bug but we don't exactly
know if it really works. At least the problem is gone on my machines. :-)
