I spent a bunch of time looking at this and concluded that the problem was
the result of changing the terminal modes from cooked to raw and back at
every line boundary.

The workaround is to turn off line editing (and the terminal mode
switching) before pasting a large number of characters into the input
buffer.  This has been tested and works.
