code review 154180043: undo CL 145150043 / 8b3d26697b8d

undo CL 145150043 / 8b3d26697b8d

That was complete failure - builders are broken,
but original cl worked fine on my system.
I will need access to builders
to test this change properly.

««« original CL description
runtime: handle all windows exception

Fixes issue 8006.
