[New issue] Importing & reloading module leaks memory</span> <a href="http://ironpython.codeplex.com/workitem/33650">view online</a></div><p>User ripedbone has proposed the issue:</p><p>"When I'm importing a module with __import__ and then reloading it with reload, it seems to leave the whole module into memory.<br /><br />Here's a simple example code how to reproduce this. It's just importing and reloading a module which has two classes and the other one has a long list of methods just to get the module size bigger.<br /><br />Garbage collection doesn't do anything with the memory until memory usage is ~600 Mb, which is quite strange. Furthermore, this maximum memory size is directly linked to the size of the imported module. Does anyone have an idea why? Or should I do the importing and reloading differently?<br /><br />Just run attached import_test.py to reproduce the problem."</p></div><div class="footer"><p>You are receiving this email because you subscribed to notifications on CodePlex.</p><p>To report a bug, request a feature, or add a comment, visit <a href="http://ironpython.codeplex.com/workitem/list/basic">IronPython Issue Tracker</a>.
