service network device interrupts and network timeout events. This |
thread should have higher priority than the background network |
thread. It is reasonable to set this thread's priority higher than |

If this is enabled, the fast network thread will tickle the |
device(s) periodically, to unblock them when the hardware has |
become wedged due to a lost interrupt or other hardware |
race-condition type problem. |
This is not necessary if a networked app is running which sends |
packets itself often - or |
uses TCP, or any similar protocol which exchanges keep-alive |
packets periodically and often enough. |
Trying to send a packet passes control into the driver; this is |
sufficient to detect and unblock jammed hardware." |

description " |
The default is 50, which will usually mean a delay between |
tests for 'stuck' devices of 500mS, that is half a second. |
The overhead only applies if no network activity occurred, |
so it may be acceptable to make this value very small, |
where high CPU load does not matter during network idle |
periods, or very large if your application tries often to |
send packets itself." |
