dropping a table with Key_blocks_not_flushed

[Eric Jensen]

Does anyone know how difficult it would be to change the behavior of  
delay_key_write so that if you drop a table which has some  
Key_blocks_not_flushed they are invalidated but not flushed to disk  
before the table is removed?  I see that if I write a bunch of rows  
and then drop the table the .MYI file grows to the appropriate flushed  
size before it is removed.

thanks,
eric
