Unplugging/plugging back in ethernet cable disrupts network access for 40 seconds

This may sound like a stupid question, but why does it take
about 40 seconds to regain network access after unplugging
and plugging back the ethernet cable?
I am running version 2.4.12 of the kernel and have a 3Com
3c59x ethernet card. I ran ping to the next router and was
receiving steady replies; I then unplugged the cable and
plugged it back in; ping received the first reply back in
about 40 seconds. The machine is configured with a static
IPv4 address, but I've seen the same behaviour with a DHCP
configured machine and a different network card, so I figured
it must be caused by the Linux kernel.

Is there any way to reduce this 40 second delay to something
acceptable, like 5 seconds or less?
