Subject: Simply return from worker listener instead of throwing when no data is received from... 
X-Git-Url: https://git.codecow.com/?a=commitdiff_plain;h=cf1a15a942444d782d4840db6df7d9cce89f592c;p=libnemo.git

Simply return from worker listener instead of throwing when no data is received from main thread since `onerror` events trigger a full shutdown at this time.
