Subject: xterm loses data (pts regression?)

First noticed it after upgrading to v2.6.31-rc5-246-g90bc1a6, still happens
in rc5-381-g7b2aa03.
If i press ^S in an xterm the output stops as expected, but after a ^Q i see
only the newly written data, everything in between is lost. Like:

> for i in `seq 1 111`; do echo $i; sleep 1; done
1
2
3
4
9
10
11
12
13
^C

[typed ^S after '4', then ^Q after a few seconds]

If the command doing the printing exits before the ^Q is sent, i don't get
any reaction to the ^Q at all, which is why i initially thought it to be an
xserver bug.
Text consoles are unaffected, output resumes as it should.
