[RARING][SRU][PATCH] Fix for LP#1208740

[Chris J Arges]

SRU Justification:

Impact: Large pastes over 4KB in a console may not be pasted correctly.

Fix: A patch was posted here https://lkml.org/lkml/2013/9/3/539, that resolves the issue. It is not upstreamed yet, pending additional analysis.

Testcase:
1. gedit /usr/share/common-licenses/GPL (replace " with blanks)
2. select all and copy contents
3. open a terminal type "
4. paste contents

If the whole contents are pasted without any errors then we pass.

Additional Notes:
While this isn't upstreamed yet, this has already been accepted into Saucy and no additional bug reports or regressions have been detected yet. It would be useful to continue to monitor the upstream thread, and/or more deeply review this patch for potential deadlocks and contribute to the upstream discussion.
