If there's a UNIX-compatible system on the planet, capable of supporting
Ethereal, with a default maximum number of open files less than 10, I'm
curious why it's so limited. I think it was higher than that in the
Bell Labs Research release accompanied by the manual "The UNIX
Time-Sharing System, Seventh Edition" (I seem to remember it being
boosted some time between V6 and V7), and that ran on Boring Old
PDP-11's, so unless we're talking Linux or BSD on a Palm, I suspect we
can handle 10 ring buffer files with no problem. :-)
