When shutting the system down, the invocation of "pump" in /sbin/ifdown 
hangs.  Sometimes I can unhang it by unplugging the ethernet cable from 
the computer.  A terrible workaround is to kill the running pump process 
manually before shutdown.  A good workaround is to run dhcpcd instead of 
pump.

Reproducible: Always
Steps to Reproduce:
1. # su root
2. # shutdown -h now
3. Watch for the line "Shutting down eth0: ".  The shutdown hangs after 
this line is printed.
	

Actual Results:  The shutdown hung with the cursor sitting to the right 
of "Shutting down eth0: ".

Expected Results:  The system should have shut down.

I'm using the supplied network card driver /lib/modules/2.2.16-
22/net/rtl8139.o with a D-Link DFE-530TX network card.  Upgrading 
rtl8139.o to the latest version had no effect.

WORKAROUND: Using dhcpcd instead of pump in /sbin/ifdown eliminates the 
problem.

I have seen dozens of reports of this problem in linux mailing lists -- a 
google.com search for "eth0 shutdown hang" will show them.

dhcpcd is now the default DHCP client in RHL rawhide...

Apologies for the unresponsiveness of the previous pump maintainer...
