Deadlock in Multiprocessing on Linux, in case GDAL 3.2.1 is installed.

AROSICS hangs during computation of the tie point grid. This only happens on Linux in case GDAL version 3.2.1 (or higher?) is installed.

> COREG_LOCAL(...).correct_shifts()

Initializing tie points grid
Equalizing pixel grids and projections of reference and target image
Warping progress |==================================================| 100.0%
Complete => 0:00:00
Calculating tie point grid (144 points) using 4 CPU cores
progress: |=-------------------------------------------------| 1.4%

This could help to find the reason of the deadlock: https://github.com/OSGeo/gdal/commit/258d73a17b1f7e93c9cf9b60a2411545d51879de
