Expected behavior and actual behavior.

ERROR 1: Failed to acquire WarpMutex in WarpRegion() on source single channel 16bit image of size 93723, 33409.

Steps to reproduce the problem.

gdalwarp --config GDAL_CACHEMAX 4096 -wm 512 -multi -co TILED=YES ^
-co COMPRESS=ZSTD -t_srs EPSG:3579 -r mode -co predictor=2  ^
 IN.tif  OUT.tif

Operating system

Windows 10 Enterprise, Version 10.0.19041 Build 19041

GDAL version and provenance

GDAL 3.1.4, released 2020/10/20 via Qgis v3.16.

Analysis

I see that in the -multi mode, the I/O threads waits for a maximum of 10 minutes for the computation thread to have finished. And you likely hit that limit because of the large value of -wm you set. There's no reason we max at 10 minutes however.
