That also changes the value for the host. I don't know if that is an issue or not.

I'm currently doing a full build with all tests and the latest shadow version.
I notice on my current kernel I have CONFIG_LEGACY_TIOCSTI=y so 
/proc/sys/dev/tty/legacy_tiocsti is set to 1.  I didn't do that explicitly.  It 
probably depends on the host distro.

I'll see what the results are when it's done.  I'm building at -j4 for timing so that 
will take a while.
