The call will block until either a reply/error has arrived to the
call, or it timeouts. In this case, I'd assume that whatever method
you're calling, it probably returns a reply indicating success (or
failure) to your application via libosso as soon as that particular
operation (say, opening an URL) has succeeded, allowing the execution
of your app to continue. One way of doing what you want might be to
listen for the disappearance of the browser service with D-BUS (and
hope that it's gone because user closed it, instead of a crash :), but
this is just a quick idea.

(as a disclaimer, it's been a while since I've used the osso_rpc_*
calls myself, so my knowledge might be obsolete and misleading)
