Actually, this code is not MP-safe, that is, usage of shmsegs without
shm_lock held. Additionally, it does not take into account the case of
reallocation. Usage of shmsegs/shm_lock in compat code do not look good,
perhaps some cases might be moved to the native module? I am not sure..

Why l_shm_segsz in struct linux_shmid_ds is not size_t too?
