In general I’d suggest making this configurable somehow and only turn it on if you’re actually debugging. It’s unfortunate that we can’t offer both debugging & collectability but right now that’s simply a limitation of the CLR and/or our lack of a separate VS debug engine which can debug Python code.</span></p>

</p><p class="MsoNormal" style="text-align:left;direction:ltr;unicode-bidi:embed"><span style="color:#1F497D">My guess is that’s code in the JIT heap that’s building up but I’m not 100% certain.
