Shell: Block on the existing event loop instead of pushing a new one

Browse source 
This patch makes `Shell::block_on_job()` pump the event loop while the
job it's waiting for hasn't finished.
As this no longer pushes new event loops, it has the effect of
flattening the stack as well.
Fixes #4976.
