imbalanced-learn: [BUG] SMOTEEN and SMOTETomek run for ages on larger datasets on the new update

I’ve been using SMOTETomek in production with success for a while. The 0.7.6 version runs through the dataset in around 5-8min. Updated and the new version ran for 1,5h before I killed the process.

               balancer = SMOTETomek(random_state=2425, n_jobs=-1)
               df_resampled, target_resampled = balancer.fit_resample(dataframe, target)
               return df_resampled, target_resampled
