It is enought to call cl_boot once. Calling it a second time won't do<br />
any harm, but the cl_boot isn't thread-safe, so don't call it twice at<br />
the same time from different threads.<br />
<br />
After calling cl_boot once you should be able to work with lisp from any<br />
thread.</blockquote><div> </div><div>This "working with lisp from any thread" I have tried, and got segfaults and corruption immediately.
