If the application is doing something insane and burning up all
of the system's file handles, then I wouldn't expect the DHCP
client to be able to overcome that.

I can't think of any use-cases for our products where the DHCP
client should ever give up. Telling customers they have to
guarantee the power-up sequence of various portions of their
plant to make our DHCP client happy isn't really an option. ;)
Am I missing something? Are there situations where giving up
on acquiring an address is the right thing to do?
