  Please check the mail archives, this generated a relatively large
thread last  month:
     http://mail.gnome.org/archives/xslt/2002-April/msg00093.html

 I don't see any reason why xsltParseStyleSheet.. should have specific 
reentrancy problem unless you blew up some of the global states of the libxslt 
or libxml2 randomly from another thread while it is being handled.

  From the feeedback and your report of attempting to put lock around
libxslt there must be something else, either in your use of the libxml2
or libxslt API, or something else. 

  Others have suceeded doing so, maybe they can help you,
