I do not see a problem with aborting. Why should the entry call be
aborted?
After elaboration of the declaration part of Req, at the begin
keyword, the task T starts and is blocked at entry Original_Call.
Concurrently the main task proceeds to the select statement, where it
waits at most 1 s for the rendezvous to take place. Since T is already
waiting there, the rendezvous takes place, so the "or delay" is never
executed. The rendezvous terminates after 3 s, and T goes into the
infinte loop.
The main task, the master of T, now waits for T to terminate (which
will never happen), so the process never ends.
This is not an asynchronous select:
select
delay ...;
then abort
Original_Call;
end select;
