Hello.

Just upgraded to STABLE-15 to test stuff. Custom kernel, customized base, but dhcpcd was working flawlessly on STABLE-14 just before upgrade.

compatXX ports are installed, system is cleaned after upgrade (yes | make delete-old; yes | make delete-old-libs)

When issuing dhcpcd -x this happens:

sending signal TERM to pid 4289
waiting for pid 4289 to exit
pid 4289 failed to exit

Base dhclient is getting IP in a second or two. Same applies to other interfaces, like ue0.

Big thanks for your project!
