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
