okay. this is weird because i did try this. had one shell window do
this:

while true; do
  echo "now..."
  (echo "testing"; date) > /tmp/myfifo
done

and yes, while the loop would only repeat after a read to the pipe,
the output from the pipe was a little weird. so while running the
while loop in one window, here's what i did in the other:

~> cat /tmp/myfifo
testing
Sun Nov 19 23:16:06 EST 2000
~> cat /tmp/myfifo
testing
Sun Nov 19 23:16:08 EST 2000
testing
Sun Nov 19 23:16:08 EST 2000
~> cat /tmp/myfifo
testing
Sun Nov 19 23:16:13 EST 2000
testing
Sun Nov 19 23:16:13 EST 2000
~> 

why then the duplicates???
