I found a following solution to make it happen while waiting for
somebody to be generous enough to take on the --post-service-hook
(unfortunately i'm not a C guy):

It is using 'at' command. The access-hook script has:

echo "delayed-notify.bash $@" | at now

while delayed-notify.bash has:

sleep 10
curl ...

This is not perfect and in certain situations can still fail because
the delay is not long enough but this will at least resolve 90% of
issues.

I hope that might be helpful for someone.

Thanks,
Eugene
