Fix: wait for initial statedump before proceeding to the main program

In the case of short lived applications, the application may exit before
the initial statedump has completed.

Higher-level trace analysis features such as translating addresses to
symbols rely on statedump. That information is required for those
analyses to work on such short-lived applications.

Force the statedump to occur before handing the control to the
application.

Fixes #1190
