The mock is an R6 object containing a rawConnection, along with a finalizer that closes this connection when the object is removed. So far so good. I’ve recently been getting CRAN errors due to the rawConnection not being closed in examples

While it is possible to hide all that inside a \dontshow{} block, it appears to me that it would be better if cleanEx() did a cleaning of the environment along with a single gc call prior to performing any checks on the end state. Is this something you would consider?
Wouldn't it be possible for you to add a way to explicitly request the
connection be closed? Then the finalizer would only need to close it if
you forgot.

This message was fine, but sometimes posting in HTML makes your message
