I've answered a similar question in the past 2 weeks; have a look in
the archives.
Basically, that's how the "selection scripts" are written (by the
linkers: commonly std or xs): they wait for the body to have been
fully loaded (DOMContentLoad event or equivalent). Moreover, using the
std linker (the default one) adds a small additional delay because the
application's code is loaded within an IFrame, that makes it totally
"asynchronous".
If you really *need* such "synchronous" loading (beware that you won't
be able to use RootPanel.get(...) on elements following the script,
and that appending to the body element --RootPanel.get(), without
argument-- will cause IE to blow away), you'd have to adapt the "xs"
linker (class XSLinker) and it's selection script (XSTemplate.js).
