In fact, it acquires it.

Unfortunately, there is no way to suppress acquisition (unless
you are ready to pass in an argument explicitely).

Looking at the code ".../Shared/DC/ZRDB/sqltest.py" it appears
as if you could pass "''" (the empty string) to mean
(no value provided) for all optional "sqltest" variables with
a type different from "string".
