+<p>Starting with 2.4.7, libxml makes provisions to ensure that concurent
+threads can safely work in parallel parsing different documents. There is
+however a couple of things to do to ensure it:</p>
+<ul>
+<li>configure the library accordingly using the --with-threads options</li>
+<li>call xmlInitParser() in the "main" thread before using any of the
+ libxml API (except possibly selecting a different memory allocator)</li>
+</ul>
+<p>Note that the thread safety cannot be ensured for multiple threads sharing
+the same document, the locking must be done at the application level, libxml
+exports a basic mutex and reentrant mutexes API in <libxml/threads.h>.
+The parts of the library checked for thread safety are:</p>
+<ul>
+<li>concurrent loading</li>
+<li>file access resolution</li>
+<li>catalog access</li>
+<li>catalog building</li>
+<li>entities lookup/accesses</li>
+<li>validation</li>
+<li>global variables per-thread override</li>
+<li>memory handling</li>
+</ul>
+<p>XPath is supposed to be thread safe now, but this wasn't tested
+seriously.</p>
