Subject: IO.popen on Windows to filter stdout

Hello all,

I've been googling and playing with this for a while, but I'm stuck
and I figured I'd ask in case anyone's done this before.

I'd like to use IO.popen, or something similar, to 'filter' the spew
coming from another programs stdout. I think I understand that I can
capture the stdout stream returned by IO.popen by using .readlines,
etc... But it still seems that the sub process is writing the output
directly to $stdout...

Of course, this is on windows, so I don't have proper fork, etc...

Is there a way to somehow "swallow" the stdout from the sub process so
it doesn't make it directly to the ruby process' stdout?

Thanks in advance for any insight,
-Harold
