- When a MyISAM table which belongs to a merge table union and is 
  renamed the associated file descriptors are closed on windows.
  This causes a server crash next time an insert or update is 
  performed on the merge table.
- This patch prevents the system from crashing on windows by
  checking for bad file descriptors every time the MyISAM table
  is locked by associated the merge table.

 - When an ALTER TABLE RENAME is performed on windows, the files are closed and their cached file 
   descriptors are marked invalid. Performing INSERT, UPDATE or SELECT on the associated merge
   table causes a server crash on windows. This patch adds a test for bad file descriptors when a 
   table attempts a lock. If a bad descriptor is found an error is thrown. An additional FLUSH TABLES
   will be necessary to further operate on the associated merge table.
