Thanks, Martin. I added the patch to the patchkit.
BTW
The motivation for really large address space spaces is actually not really
to use that much memory, but just to be able to mmap extremly large
files. The original reason I started this was because some users wanted
to mmap 300GB files and it didn't work because the shared
libraries were in the way. So if you consider that it may be worth
enlarging it at some point anyways. I assume S390s have typically
more storage than x86-64 machines ;-)
