^D becomes ^L on my VAX Console? - (nf)

The reason your system goes to sleep printing on the console is that the
unix kernel console printf busy waits at some absurdly high IPL, thus
providing reliable debugging output.  This is a feature, I believe.  Lucky
you.  I could flame about robust operating systems and attention to detail,
but there really isn't much point in it.
