Hm, I believe !netreloadmodule should block until the module is fully loaded. (otherwise I'd be able to load modules in parallel on startup, which it doesn't) !netunloadmodule otoh, does NOT block. (until !unloadmodule does)

However, I suspect there may be a problem with !reload. iirc omar had trouble with it in a script, and I couldn't get it to update $vars$ at all from lsxcommand. :/
