/*
* History:
* --------
* 2003-06-29 added shm_realloc & replaced shm_resize (andrei)
* 2003-11-19 reverted shm_resize to the old version, using
* realloc causes terrible fragmentation (andrei)
* 2005-03-02 added shm_info() & re-eneabled locking on shm_status (andrei)
* 2007-02-23 added shm_available() (andrei)
* 2007-06-10 support for sf_malloc (andrei)
