@jzonthemtn imho this issue also deserves some (new) attention in order to
use the `MorfologikLemmatizer` in multi-threaded environments. The question
would be, if we want to stick with `synchronized` or just create & dispose the
`DictionaryLookup`.

> The method lemmatize of MorfologikLemmatizer is not thread-safe.
> Concurrent invokes may rise exceptions and return unpredictable resutls.
> It seems that the whole method must be sync because the variable returned by
> the morfologik lib is shared between threads.
