Due to the defects of our disk allocation algorithm, the first byte of free'd empty space will never get used. Please, fix this problem.

Due to an unknown bug in either mdb_data_alloc or mdb_data_free, or even mdb_write_data, we have to waste one more byte.

This occurs at what stage of storing data (flush/initialize/or something else)?
