Solution：

c = pycurl.Curl()

c.setopt(pycurl.URL, ‘www.baidu.com’)

c.setopt(pycurl.FOLLOWLOCATION, 1)

c.setopt(pycurl.NOSIGNAL, 1) #need to add

c.setopt(pycurl.TIMEOUT, 1)
Reason:

This will tell libcurl not to use any signal related code that causes in a multithreaded python script this kind of error.
