Heh, when I did the port to PPC I ran across an error like this, and
realized that if you ask for 880M of RVM data, RVM will want to grab 880 M
of virtual address space, leaving only 220M (I *think* x86 and ppc get a
gig of VM..) for program code and thread stack space. Maybe an Alpha would
be happier with this, with 64 bit addressing and all... 

Didn't someone discuss the possibility of modifing RVM to not require so
much VM at one time? Maybe now would be a good time to push to get kernel
modifications needed to allow this?
