Well, here is a "strace -vTi ifconfig eth 192.168.1.3" from the
output I can see that it spends a lot of time (the number in<> at
the end) in that ioctl before it fails, but I don't know why
[4007d564] ioctl(5, SIOCSIFFLAGS, 0xbffff870) = -1 EAGAIN (Resource temporarily
unavailable) <0.390989>
If you tell me how to trace it I could try it...
