Can \XeTeXinterchartoks hang ?  I have just added two debugging
strings to my earlier (apparently working) code, because I became
aware after changing font as well as language at a boundary point
that something odd was happening, and now the code hangs.  This
is the augmented code :

> \XeTeXinterchartoks 0 \Greek {\uselanguage {greek}(Greek)}
> \XeTeXinterchartoks \Greek 0 {\uselanguage {UKenglish}(English)}

and this is the original :

> \XeTeXinterchartoks 0 \Greek {\uselanguage {greek}}
> \XeTeXinterchartoks \Greek 0 {\uselanguage {UKenglish}}
