--- Comment #1 from Heiko Schlittermann <hs@???> ---
A boiled down variant of the configuration that lead to this issue:

    acl_smtp_rcpt = accept
    perl_startup = sub foo { local $SIG{ALRM} = sub { } }
    begin routers
        test:
            driver = accept
            condition = ${perl{foo}}
            transport = test
    begin transports
        test:
            driver = pipe
            command = sleep 2
            timeout = 1s


It can be tested easily using `<<<test exim -odf -C ... -v hans@???`,
the
transport dies with signal 14 (SIG_ALRM). But should end with a normal message,
stating a timeout occured.
