Current version of arpd included with iproute2-2.6.37 will fork 
unconditionally on start-up (using daemon() library call). This causes 
problems with distro start-up scripts, as PID of the started daemon can not be 
reliably obtained, hampering orderly daemon shutdown process.

The included patch makes arpd write it's own pid file after fork, in a common 
LSB fashion, so as to better inter-operate with start up scripts. Removal of 
stale pid files is handled elsewhere.

I already checked in a version which has the -p pidfile option.
