Description

If the user does not select an appropriate resolution for the resulting raster(s), it risks to get stuck with an excessive resolution, and too long processing time. I suggest to do a simple calculation of the resulting number of pixel before running analyses, and warn the user if this is too high.

I think this request could be satisfied by instead allowing cancellation of gdal algorithms. The native QGIS algorithms all have nice progress reports and support responsive cancellation already.
