Tester not working with linked list !

[salecler]

Hi, you're tester is really good but it isn't done for people who done it with linked list because we will always have a timeout with big line at buffer_size 1.
Trying to print 3000 characters with a buffer_size of 1 with linked list, will create 3000 new nodes. And even if it doesn't last more than 200ms it will always give timeout.
Thanks !
