(multiprocess) Error for high PODG concentrations

[DSeiferth]

Hi everyone,

I used the demo script to analyze lipid interactions for varying concentrations of PODG (diaglycerol).
For performance, I have deleted all water molecules in the xtc file before starting the PyLipId analysis.
For low concentrations (1%, 5%, 10%), everything works fine.
For higher concentrations (20%, 40%), I get the following error when analyzing the bound poses:

^MANALYZE BOUND POSES: 0%| | 0/19 [00:00<?, ?it/s]^MANALYZE BOUND POSES: 5%|▌ | 1/19 [2:15:25<40:37:47, 8125.95s/it]^MANALYZE BOUND POSES: 5%|▌ | 1/19 [2:15:26<40:37:49, 8126.06s/$
