git-daemon hangs after invalid request

Hi,

I noticed git-daemon hangs sometimes...

    git clone git://example.com/git/repo.git

works just fine but this

    git clone git://example.com/git/invalid.git

hangs and I have to hit ^C. It's OK but error message would be nice. git-daemon outputs these lines to syslog:

    Request for '/git/invalid.git'
    '/git/invalid.git': unable to chdir or not a git archive

Now if I try to clone the existing repo again

    git clone git://example.com/git/repo.git

it hangs. I have to restart git-daemon to get it working again. I started git-daemon (1.4.2) with --syslog --verbose flags.
