No, it's not a bug, it's simply that a fix to another problem has made
it a little harder to background jobs in a hook script. You have to
make sure that all the file descriptors the job opens are closed, or
svn will wait for them to be closed (i.e. when the the process exits).

On unix you'd do that like this:

long-running-command >> /dev/null 2>&1

Of course, if you want to see the output you should redirect it to
someplace other than /dev/null.

There is some equivalent on Win32, but I'm not a windows person so I
don't know the details.
