svn 1.3.0: post-commit hook waits even if tasks are backgrounded

we upgraded from subversion 1.1.4 to 1.3.0 yesterday, and i noticed
that tasks from a post-commit hook can no longer run in the
background.

for example, a post-commit hook of

    #!/bin/sh
    sleep 10 &

waits 10 seconds when a commit happens, like so:

    $ time svn ci -m "dummy checkin to test speed of checkins"
    Sending custom/compile-1.0/bin/compile
    Transmitting file data .
    Committed revision 414.

    real 0m10.940s
    user 0m0.080s
    sys 0m0.072s

when the same hook is run from the command line, it returns instantly:

    $ time /opt/repos/hooks/post-commit

    real 0m0.009s
    user 0m0.002s
    sys 0m0.007s

this isn't the way it used to work. is there a workaround?
