Yes, Michael that is the ideal solution. I was hung up on the OP's concern
over globals. But you can even do the same thing with globals by using the
"local" declaration:
while (1)
{
do_stuff();
sleep 30;
}
sub do_stuff
{
local ($var1, $var2);
# load huge stuff into $var1, $var2, etc.
# these are globals that can be seen in any sub called
# from here (unlike "my")
# when do_stuff ends, "local" copies of $var1 and $var2
# are freed
}
This is a technique I use every day in my Apache::Registry scripts.
