Ok,

Which was a wrong guess...

I did one more test, and the problem can indeed be located to the konsole's
pty/session code.

I made a test with a variant of the konsole that uses forkpty(3), which does the
pty and session stuff right. ./termtest was cleaned up then as it should under su.

Not using forkpty and mess of replacements and hacks around ptys instead, was
historically due for the unavailability of glibc2 under many systems at that time.
