[Bug 1066351] Re: upstart ftbfs in quantal on arm*

[Andy Whitcroft]

@James -- ok I can trigger this error from the test program as well on
amd64.  However after some poking I think this test case is flawed.  I
made the read retry if it did not see a 14 long string and in the tests
I have run all failures show the newline is there:

    loop 39225 of 99999
    ret = 14
    loop 39226 of 99999
    ret = 12
    ret = 2
    ret = -1

So I suspect that the pty newline mangling is allowing this single write
at the dash end to be split into two read at your consumer.
