# Re dlz/mysql and threads, needs to be verified..
# MySQL uses thread local storage in its C api. Thus MySQL
# requires that each thread of an application execute a MySQL
# thread initialization to setup the thread local storage.
# This is impossible to do safely while staying within the DLZ
# driver API. This is a limitation caused by MySQL, and not the DLZ API.
# Because of this BIND MUST only run with a single thread when
# using the MySQL driver.
