This is part of an investigation of a non-deterministic reference leak. While we're looking for the root cause, this is included temporarily so that CI doesn't fail on this particular issue. This enables it to find other regressions in the meantime, which would otherwise be shadowed by our known issue.

by raising an error but by sending empty data to the read

`pty.spawn` calls.

bpo-44752: Make rlcompleter not call `@property` methods (GH-27401) (GH-27444)

* rlcompleter was calling these methods to identify whether to add
  parenthesis to the completion, based on if the attribute is callable.
* for property objects, completion with parenthesis are never desirable.
* property methods with print statements behaved very strangely, which
  was especially unfriendly to language newcomers. <tab> could suddenly
  produce output unexpectedly.
