DeepLCFeatureGenerator multiprocessing issue when number of processes is more than 1

[vrkosk]

When I run DeepLCFeatureGenerator with processes=8, it takes a long time, much longer than processes=1. Python correctly starts 8 python.exe multiprocesses, but often the execution just hangs (I've waited more than 30 minutes -- using processes=1, it took less than 5 minutes). It's actually faster to run DeepLCFeatureGenerator with just processes=1 and it seems to work every time.

I can provide a test case if this isn't a known issue already.

Hi, there have been some significant updates lately. Can you confirm for the latest versions this is still an issue.

It will be a while before I can test the latest version, sorry.
