Have you checked logs to make sure that its not issuing errors? Is the
DROP process doing anything? All DROP TABLE does is rm the appropriate
files on teh file system and update various system tables to remove
references to it ... how big is this file, that its taking >24hrs to
*delete* it from the file system?
