This is a known problem of script/server. Ctrl+C seems not been trap
and requires a page hit to make it work.

I recommend usage of mongrel_rails as you decided to do later here...

Is not related to mongrel but a bad trap of INT signal by script/server.

There is no known workaround up to date, this even fails if you use
another server like Thin instead of Mongrel.

Has been recommended use mongrel_rails start instead of script/server
for quite some time, specially on Windows due this signal trap bug.

Please let us know any other issue you're having with this.
