That's because the server is completely single-threaded, so it blocks
on processing everything else until the hook returns.

What your hook _can_ do is spawn an independent process and return
immediately, letting that process do its thing...

I don't know offhand if we have a spawn-in-background function exposed
to hooks, though even if we don't, you could hack it by executing the
shell and putting "&" at the end of your command line :-).
