Thanks all - the target platform is perl 5.6+, so I guess the bug tilly mentioned won't be an issue. I've got this working the way I want now (well - the way I want for an alpha relase :-)) and I've decided on the following: 
sub execute {
    my $self = shift;

    my $req = BigHairyDatabaseInteraction->new(...);
    {
        local $SIG{INT} = sub {$req->{_signal} = 2;
                               $req->handleInterrupt; };
        local $SIG{TERM} = sub {$req->{_signal} = 15;
                                $req->handleInterrupt; };
        $req->executeRequest();
    }
    # If a TERM/INT signal has been delivered during the request
    # then pass it on to the program itself:
    if($req->{_signal}) {
        kill $req->{_signal}, $$;
    }
    ... rest of $sth->execute()

The idea is that I want to override any signal handlers that the calling program may have installed so that I can interrupt the processing on the server as needed, but I also want to make sure that the caller does eventually receive the signal.

So far this appears to work really well...
