I don't know why time.sleep(0.01) statement is needed, but it is the source of the bad behaviour. If the sleep statement is removed, the behaviour fades away.

#file: /master/wexpect/host.py    
#line: 828
   # Still have time left, so read more data
                self.isalive()
                c = self.read_nonblocking(self.maxread)
                freshlen = len(c)
                time.sleep(0.01) #<-- 
                incoming += c
