I confirm this effect and you don't need a fat application to 
demonstrate it. With this Windows cmd script loop.bat:
@echo off
set n=0
:loop
echo %n%
echo %n% >> .log
set /A n=%n% + 1
ping 127.0.0.1 -n 2 > nul
goto loop

run it: ./loop.bat, then use ^S; the script will actually continue to 
run but will not show any more output in a pty-based terminal (works in 
Cygwin console).

Thrashing? Might be caused by the apparently-stopped application going 
into some endless-loop activity.
