a single file could be required multiple times &#8211; if you do $&#8221;.clear
before calling require. I need to figure out what is exactly the condition

<p>With the latest version, if a ruby source file requires itself, or if there
is a cyclic chain of requires so that the original source file is required
again - it results in an infinite loop.<o:p></o:p></p>

<p>&nbsp;<o:p></o:p></p>

<p>This used to work correctly in the previous version&nbsp;-&nbsp;it simply
requires marking the file as already loaded prior to executing it.<o:p></o:p></p>
