jobs: Ensure releasing event loop

The internal functions blocking threads
for implementing call_sync were not releasing
the event loop, leading to deafness of the
binder.

Include a tuto-4 that reproduce the issue
on a binder with the bug and that also shows
interesting usages of the binder.

Bug-AGL: SPEC-2161
