Review Comment:
   I don't know if applicable but a common patter is to have a _lock_ instance 
and lock on that
   
   ```java
   private final Object lock = new Object()
   
   public void waitUntil(Predicate<Sequence<?>> pred) throws 
InterruptedException {
       synchronized(lock) { ... }
   }
   ```
   
   but this is really a nitpick, so as you explained the issue may be also 
happen somewhere else
