Quota option seems to leave wpull hanging

[newmanships]

What I wanted: (Describe briefly what you want to achieve here)
Using Quota option for wpull to stop after X amount of bytes have been downloaded to warc file
What I expect: (Describe briefly how you think the program/feature will work)
It stops crawling when it hits the quota, but leaves Wpull hanging (see output below):

The command or website causes the problem: (Copy the options provided to Wpull here)
wpull http://www.techcrunch.com --quota 1000000 --warc-file techcrunch.com -rH --warc-cdx --level 2 -Dtechcrunch.com --no-check-certificate
Reducing the quota amount below this amount works as expected, for example:
wpull http://www.techcrunch.com --quota 100000 --warc-file techcrunch.com -rH --warc-cdx --level 2 -Dtechcrunch.com --no-check-certificate (one less 0)
Operating system: (Write your OS name here such as Windows 10/Ubuntu Linux 14.04 32-bit/OS X 10.10)
10.11.6
Python version: (What does python --version say?)
3.6.1
Wpull version: (What does wpull --version say?)
2.0.1
