I think you have to redirect stdout and stderr to a file (or to
/dev/null if you wish). Something like:

$REPOS/hooks/delay.sh 2>&1 >logfile &

should do the trick.

I do this with my post-commit hook as well (for sending out commit
emails, don't want that to delay the commit), and it works perfectly.
