Issue Description

We had reports of some tools within our company that used axe-core crashing because of memory issues on certain pages. Someone investigated this and found 2 places where VirtualNode references are retained after teardown().

1. recycledLocalVariables
2. channels

The second one seems to be causing the most issues. There's a timeout, but it doesn't seem to clean up the handlers.

This is not a blocking issue for us right now. We have a way of working around it in our tools, so it's not as high of a priority for us to get resolved as it would be otherwise.
