I am sorry my scenario was not clear.

Normally, VC commands fail when I have not previously specified my ssh
passphrase so CVS can contact savannah.  Emacs does not know how
to promptfor the passphrase on their behalf.

So normally I specify the passphrase in advance with ssh-add.

That time I forgot to run ssh-add, so the basic vc commands should
have failed.

But vc-dir didn't report a failure.  Instead it created the buffer
with no failure report, and then the buffer was nonresponsive to
commands.

The bug is that vc-dir did not fail when it should have failed.
