Thanks! And that was fast!

Allowing DEFAULT-READ-ELEMS to be set from the environment's a good
idea that I hadn't thought of- since it is a machine-dependent
performance tweak, letting it be set outside the code is a good idea.

I had originally envisioned this as an "option" to "sub open" for
fine-grained control as to which IO::Handles got what
DEFAULT-READ-ELEMS, but I'm not sure it belongs there. After all it is
a performance-related tweak and I'm liking the idea of it being
primarily set from the environment; setting it in the code means
you're writing something for a particular host, don't need to change
the spec to support that.

Is there anything similar on the "write" side- output buffering- that
could use this treatment?
