[asterisk-users] Clearing variables in the dialplan?

[Rushowr]

Hello all,

Wanted to toss out a question that I've been looking into for some time now
with no real results. When a variable is given a value in the dialplan, that
obviously will take up a little memory. If you're running a rather
large/complex dialplan, you may end up with variables you don't need after a
while. What do you think is the best way to clear these out and free up
memory? Currently I use:

	Set(varname=)

To tell asterisk to set it to a null value. Any thoughts?
