When we encounter many dead textures, we want to GC. Textures can take up fds (potentially even more than 1) and when we are not collecting them quickly enough, we may run out of fds. So GC when more then 50 dead textures exist. An example for this happening is recent Mesa with llvmpipe udmabuf support, which takes 2 fds per texture and the test in testsuite/gdk/memorytexture that creates 800 textures of ~1 pixel each, which it diligently releases but doesn't GC.
