MEDIUM: checks: avoid waking the application up for pure TCP checks Pure TCP checks only use the SYN/ACK in return to a SYN. By forcing the system to use delayed ACKs, it is possible to send an RST instead of the ACK and thus ensure that the application will never be needlessly woken up. This avoids error logs or counters on checked components since the application is never made aware of this connection which dies in the network stack.
