Just as a note: the reason for introducing the version part in thread
IDs was exactly to overcome situations like this, i.e., to identify
that one is communicating with or operating on the expected thread.

If dealing with situations like this without making use of the version
part proves too problematic or inefficient you might want to
reconsider the scheme of mapping task IDs onto version numbers?
