https://github.com/balazske approved this pull request.
I did not find more issues (at least in `StreamChecker` and its tests). But did
not check in detail the `UnixAPIChecker` part and tests.

Applied the feedback.
By the way, when `StdLibraryFunctionsChecker` is refactored, I'd be happy to
give a hand if you need updating these checkers (UnixAPI and Stream).
