Consul is duplicating the open files with reload

[ab-fuze]

I was having issue with max open file error on ubuntu server 14.04 with consul consuming all the file descriptors.
I find out that on every consul reload the number of open files almost doubles this with 1.0.7 and 1.1.0

Reproduction Steps

To reproduce:
on one shell run
watch "lsof | grep -c consul"
on the next shell run
consul reload
