Subject: Linked stream handling
Some of us interpret POSIX that it requires or at least encourages a
concept of linked streams: reading on from some streams may implicitly
flush certain other streams. (The language in the standard around
that is not particularly clear.) Linked streams may introduce
deadlocks (particularly with explicit locking if flockfile), so POSIX
suggests that implementations provide some form of deadlock detection,
failing certain stream operations.
Do I read the sources correctly, and musl does not implement any of
this?
