Due to different bytes order in lck_long member of union in class Lock, upper bytes (always zero for LCK_page_space locks) are taken into an account on bigendians. This breaks normal operation of page spaces.

Makes no sense using 2-bytes long lock values - 4-bytes use same memory (it's anyway allocated aligned) and work with same speed (also due to alignment in shared memory).

Therefore lck_length is set to sizeof(long) for this type of lock.
