Never populated. MySQL doesn't open the table it wants to drop.

You have to store this piece of metadata elsewhere. For example, in the
table file, in the header. Or in a separate file, testtable.index_list.
Or on the filesystem (if all index files are called
testtable_somekey.index you can simply delete all testtable_*.index
files). Or something.
