Was there any change to the system() implementation on Windows between
1.8.4 and 1.8.5? I can only surmise that this is some bizarre
interaction between Ruby's Thread.new and the Windows CreateProcess()
function (which is how system is implemented behind the scenes on
Windows, irrc).

Also, do you get the same error if you build Ruby from scratch as
opposed to using the one-click installer?
