Are you talking about IO.popen? I didn't think Ruby used _popen()
behind the scenes, but it's been a while since I looked. The _popen()
function is basically broken on Windows. From MSDN:

"If used in a Windows program, the _popen function returns an invalid
file pointer that will cause the program to hang indefinitely. _popen
works properly in a Console application. To create a Windows
application that redirects input and output, see "Creating a Child
Process with Redirected Input and Output" in the Platform SDK."
