concurrent write myIsam holes

in the mysql manual it states that concurrent inserts only occur when no holes are present within a table? what are these 'holes' that the developers refer to? do they mean auto increment holes? if so, if a table does not have auto increment columns, does this mean it is impossible for it to have holes?

when a row gets deleted, why is there a hole?

Why wouldn't there be? There is allocated memory there, the record gets deleted, and now that memory doesn't have anything in it. Just like if you delete a file. The memory that held the file data is now free again, it's not allocated to a file.
