I don't think ? place holders work in DROP TABLE statements. AFAIK,
they only work in statements like INSERT, SELECT, UPDATE and DELETE,
and then only to represent data values - not schema related names.
I.e., I've never seen this work: UPDATE FOO SET ? = 1.

Some suggestions:

1. Fork multiple processes to perform the drop table statements (i.e.
use several database connections and processes to perform them in
parallel.)

2. How about just start using a brand-new database schema? Then you'll
start off with zero tables. Copy data from the original schema as
needed. Then you can drop the 250 K tables at your leisure.
