Comment(by tomeu):

 Tried it here, Browse started downloading the page, started rendering,
 finished downloading, and was kept rendering for several seconds. During
 this last phase, memory usage grew quickly. Memory was almost exhausted
 when rendering the page finished and 100MB of memory got released back to
 the OS. So:

  - Browse didn't caused OOM this time, but would have caused it if other
 activities were open,
  - during the rendering phase, memory was allocated but only was released
 at the end. This suggests that mozilla could be made smarter as to release
 memory as soon as it's not needed, rather than waiting for a big flush at
 the end of the rendering process.
