[development] The dawn of DB locks

[Karoly Negyesi]

Hi,

Today marks the end of explicit database locks issued by Drupal core.
Thanks to David Strauss who helped me getting rid of them by patching
cache_set and variable_set in http://drupal.org/node/55516 .

Now, do we want to keep db_lock_table ? In Drupal 6, likely yes. In
Drupal 7? The question makes sense even if go over to PDO.

Regards,

NK
