Stretching of triple and quadruple arrows could be added using extenders at U+E134 to U+E137 in STIXNonUnicode beta.

On Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 neither the double or the triple arrow extend.

STIX fonts are currently required for stretching the double arrow to arbitrary lengths: http://www.mozilla.org/projects/mathml/fonts/
Bug 414277 could provide a fallback solution when the fonts are not present.
