Description:
The debug define DEBUG_FRAGMENT_LOCK is set also in production code
in 8.0.23. This leads to excessive memory usage, it increases the
memory usage of fragment records by 4 kByte.

How to repeat:
Read code or use sizeof(Fragment record) in DBLQH.

Suggested fix:
Comment away the define in production code.
