Right; it's the build environment setrlimit() test I think that causes
the problem.

I'd have configure'ed --with-filedescriptors=N (64k, say) and forget
the ulimit in the build script wrapper and still get 1024, or whatever
the current build hard limit was.

I never bothered to look and see the details of what it was doing, but
is there any situation where the build environment setrlimit test is
actually helping? All the prod boxes had 16k, 32k, 64k hard limits;
the build box often defaulted to a lower value. Having my own minimal
script around make to ulimit unlimited first then configure and make
worked, but....
