Thank you, this was very instructive indeed.
I.e. the seqeunce

t1: Thread A enters wait
t2: Thread B signals

must result in a guaranted wakeup.
While

t1: ThreadA enters wait
t2: Thread B signals
...
tx: Thread X signals
...
ty: Thread Y signals
...

should not block off any successive signallers (X,Y,...) until
another wait is entered. My and as I learned by now your
first attempt too suffers exactly from this.

Thank you,
Roland
