Do you know which distributions have shipped with this or newer
kernel?  I was holding off mostly because I think it is only
from-scratch builders that have that newest kernels that will see this
new behavior.

I think this is a bug in glibc on kernels without a hard limit.
(However it may be a lessor of two evils it if avoids breakage of some
programs that always expect a limit.)  I wonder if libc tries to
dynamically detect this or if there is a hard coded value that needs
to be updated.  Hmm...

You say "apparently" but I am sure that it was you posted a note
elsewhere noting this change in the upstream kernel.  I followed your
reference to where it was committed into Linus' kernel tree here:

  http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b6a2fea39318e43fee84fa7b0b90d68bed92d2ba

It is only a matter of time before this propagates.  But time is also
what keeps everything from happening all at once and so we will need
to wait a bit before this shows up on most machines in the wild. :-)
