Version 2 is OK as is, if you're tired of messing with it.
You didn't have to remove the backtrace, though, if you'd
like to keep that.

I think this could be simplified to:
	gdb_test "continue" \
		"Breakpoint 2.*tf.* at .*tbug.*" \
		"continue to tf"

Similarly, your backtrace test could be as simple as:
	gdb_test "backtrace" \
		"#0 .*tf .*at .*tbug.*" \
		"backtrace from thread function"

I don't think you can predict what will be on any
higher frames, but you could test the current frame
and make sure backtrace didn't just die or show you
the wrong thread.

For this, all you need is the existing procedure call:

	delete_breakpoints
