That's perfectly normal.  The here-document or here-string payload is
written to a temporary file, which is kept open, but unlinked.  That
way, when bash closes it (or is killed) the contents are simply deleted
by the file system, and bash doesn't have to do the clean-up.

I still don't know whether your original issue is a bug or not, though.
