Comment (by zspitzer):

 At the moment I am totally avoiding using GDAL, it's not production ready
 and always seems to just crash unfortunately. It is however the easiest
 way to reproduce the problem.

 I'm pretty much working with a read-only repository which is being used to
 generate tiles for a big map using about 9.6 Gb of SDF / SHP files.
 Thankfully 2.0.2 is pretty damn stable.

 So there's two items here, like you said, the shutdown logic needs to
 abort any r/o rendering operations. For dynamic maps, ideally if the http
 connection is dropped those operations should also be aborted as the
 result isn't cached so there is no point.

 The second one is that problems with rouge FDO providers don't appear to
 be handled robustly enough and cause this stuck state. GDAL reproduces it
 the problem quite well, I have also seen this with a problematic SHP file.
