No, you don't need to clean up your variables after use. To quote from the
manual:
"All variables for a thread are automatically freed when the thread exits."
So, when you close the connection to the MySQL server, your variables are
unset automatically - but not for other connections, just your own (bear in
mind that user variables set in one thread are not available server-wide).
As for memory limits on variables, this may be one question for the
developers to answer, is it mentions nothing about limits in the manual.
