	// hour, open it back up, and try to submit a form before the CSRF refresh

	// CSRF is often quite bad (you basically lose data, or it's a big pain to
	// recover at least) and I believe we gain little additional protection
	// by keeping the window very short (the overwhelming value here is in
	// preventing blind attacks, and most attacks which can capture CSRF tokens
	// can also just capture authentication information [sniffing networks]
	// or act as the user [xss]) the 7 hour default seems like a reasonable
