I think what Ryan is alluding to is that control does not return to the
user doing the commit until the hook completes. So he thinks the hook is
a bad idea because it ties up every user doing a commit. It also ties up
the server from being able to finalize another commit.

Another solution would be to figure out a way to get your hook to fire off
the update as an asynchronous event. We do something in a hook where we
create a file with the repository and revision info in it. A daemon
process written in Java monitors the folder where this file is created and
does stuff based on the file being created. This allows the hook to run
very fast and the work is done in the daemon process.
