Trying to answer my own question. I knew it would have something to do with thermal radiation . . . I just don't know exactly how quickly such radiation would take place, and I'm pretty sure it's dependent on the materials. In the vacuum of space, it may be possible to cool down something like a rail/coil gun fairly quickly, if the right materials are used.

I guess like most technology, this is all pretty complicated. :-)
