I have also encountered this bug. I think, this is the problem of some
suse shared library which is used by C-shell. Run the following test
script on SUSE and you will face the same behavior:

#!/bin/csh -xf
sleep 10 &
wait

The same script for bash works properly. Also this script works well on
any other Linux distributions I have used. The updating of tsch change
nothing as so as the updating of the Linux kernel.

I have posted bug reports to several Linux forums and also to SUSE
developers, but nobody answered.

So, I'm going to change the Linux distribution :(
