Comment (by sjamaan):

 I'm not sure this new constant is a sane value - it's 9 exabyte if I'm not
 mistaken. No machine available today has that kind of memory (and it will
 probably take a lot of time before any machine will - though if you
 include swap that day might be closer than we think).

 What's the original purpose of the maximal heap size? It being 2GB on
 32-bit systems seems to be half the maximum addressable size (which makes
 sense if you consider that the maximum heap would be double that, but also
 a little pointless because at that point you'll have eaten up all memory
 anyway - that memory won't typically all be available. Except there's
 swap...)
