I have just changed the Font mutex I added yesterday to a static Font
mutex that is shared between all Font's.  This change ensures the
serialization of calls to freetype and clears the remaining problem of
enabling stats while running osgtext --mt.  This change in now checked

Could user check out the svn version of the OSG and test out the
changes to osgText and let me know how you get on.
