Please review 7112160 (Kumar Srinivasan)

[Kelly O'Hair]

On windows, it's more of a "give me a block of memory this big", and sometimes even if the
system has 4GB, it might not have a 1GB hole to give you. :^(  So java just dies on startup.

And if you make this number > RAM, the Linux/Solaris systems could very easily just page thrash.

We could declare that 2GB RAM is the minimum now, on all systems, and do as you say, but
there are people out there with less RAM, I think...  not me...
