+# 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.
