node_access_rebuild()- 6
node_access_rebuild($batch_mode = FALSE)
Rebuild the node access database. This is occasionally needed by modules that make system-wide changes to access levels.
When the rebuild is required by an admin-triggered action (e.g module
settings form), calling node_access_needs_rebuild(TRUE) instead of
node_access_rebuild() lets the user perform his changes and actually
rebuild only once he is done.
Note : As of Drupal 6, node access modules are not required to (and actually
should not) call node_access_rebuild() in hook_enable/disable anymore.

$batch_mode
Set to TRUE to process in 'batch' mode, spawning processing over several
HTTP requests (thus avoiding the risk of PHP timeout if the site has a
large number of nodes).
hook_update_N and any form submit handler are safe contexts to use the
'batch mode'. Less decidable cases (such as calls from hook_user,
hook_taxonomy, hook_node_type...) might consider using the non-batch mode.
