Title:
  Large pastes into readline enabled programs causes breakage from
  kernels v2.6.31 onwards

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The bug is described in detail in this mail:
  https://lkml.org/lkml/2013/7/25/205 

  This bug affects any readline enabled program, like bash or psql.  A
  "large" paste is any paste of more than 4kb of data (4kb is the size
  of the kernel buffer for reading from the console).

  As can be found in the lkml thread, the issue is caused by the
  constant change between canonical mode and non-canonical mode, done by
  readline for each line being read.  This change means that when the
  buffer is full, some characters might get lost.

  This has been happening for a long time (starting with kernel
  v2.6.31-rc5), but it was barely noticeable for a while.  Some changes
  done in the way the kernel schedules character reading in v2.6.39-rc1
  made it much more noticeable.  Even the most recent kernels are
  affected.
