Got very odd results on Debian Jessie when having the uev_private_t last in uev_t. Turns out that when uev.c set "w->active = 0;" the w->fd data member was written to instead. Placing the private data first in uev_t is better practise, generally a good thing for linked lists built on the BSD sys/queue.h API, looks a lot better, but foremost works.
