I saw lot of "systemtap eof" errors while executing weekly tests.

Here, I found a break-code(^C) which tcl code sent (as a signal) to stap.
On 2.5.24, NO ^C appeared in the output. Thus the test does not expect it.
I think that is why the test failed to catch the test result.
I'm not sure this (kernel's?) behavior is correct. It is possible that is
a regression of the kernel.

Changing all those "send \003"'s to proper "kill -INT -<pgrp>" seems to work.
