minor update
fixed core from null json
Merge branch 'master' of git@github.com:gigablast/open-source-search-engine
try to fix core from pthreads logging msgs.
include pthread.h
forgot to unlock thread lock
fix bugs of pthreads junk not being async safe.
we were calling fprintf from a signal handler
(interrupt) while fprintf was currently in progress
and the pthread junk did not like that.
