(MDB) Unexpected disk space waste

[chuigda]

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.

[chuigda]

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.

The current allocation strategy, wasting 2 bytes. see the @todo

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