[XeTeX] wrong kerning and slow processing with xelatex in texlive 2010

[Vadim Radionov]

Hi, Peter,

Sorry for annoying citing (I was not sure how to post to the same
thread rather then to start a new one, so i replied to my own messafe)
and whitespace.

I compiled the same source with 2 instances of xelatex, the one from
texlive 2010 works not as i expected (wrong kerning in small caps `та'
and in normalfont `тт').  Here is the source:

-----------------
\documentclass{book}
\listfiles
\usepackage{xltxtra}
\usepackage{polyglossia}

\def\russianfont{}
\setdefaultlanguage{russian}
\setmainfont[Script=Cyrillic]{CharterITC}
\begin{document}
\textsc{та} оттого
\end{document}
-----------------

And this is what listfiles shows:
