node_access_rebuild($batch_mode = FALSE)
Rebuilds the node access database.
This rebuild 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_install/uninstall anymore.
Parameters
$batch_mode: (optional) 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(), etc.) might consider using the non-batch mode. Defaults to FALSE.
