The scene is fine... if you have at least 17 GB memory, it renders fast
(the parsing is not that long either, yet longer than the render)
(test done on linux, with enough ram)

The top resident memory size in kbytes is 17320752, 17 320 752 kB !
(data from /usr/bin/time -f "%M" ...)

The issue is that your system has only 3GB, so it is going to use
heavily the swap... and that will crawl, whatever the action of aborting
or continuing.

The nice thing is that you use a 64 bits system. A 32 bits system would
have killed your process at the early start.
