then there is some confusion, because when i run your program
as-is (except for the bug fix) on my Plan 9 system, i get roughly the 2+ seconds you
mentioned as the time for the Linux system, and that also compares
with the time i get when i run the same code on a Linux system.  i can only get 20+ seconds
on Plan 9 IF i have the program do the unbuffered print AND redirect to a file system across the
network (if i do the unbuffered print and send the output to /dev/null, it's still about 2 seconds).
