I'll consider it for 2.9.  I think 2.8 should not change this since it 
is a stable version.

I'm not sure if it is still the case, but at one point in time on 
windows if you output a lot of stuff to the real stdout and there was no 
console window to write it to, then eventually the buffer would fill up 
and the program would be suspended until the buffer was emptied.  If 
somebody wanted to try and reproduce this on win2k, XP and Vista to see 
if it is still an issue I would appreciate it.
