Lock the right lock for unmatched subfolder list stuff. If the sub folder
2001-10-19 <NotZed@Ximian.com> * camel-vee-folder.c (camel_vee_folder_remove_folder): Lock the right lock for unmatched subfolder list stuff. If the sub folder is deleted & part of unmatched, or the last ref to the sub folder is gone from unmatched, blow it away completely from unmatched, but only do it once. (vee_folder_remove_folder): Added arg to kill unmatched unconditionally. Also handle deleted folders, always remove stuff. (folder_changed_change): Lock subfolder lock for entirety of operation, and also check to see if the subfolder is still there before doing any fancy work (incase it got removed while we were waiting to execute). * camel-store.c (camel_store_unsubscribe_folder): If we are unsubscribing from a folder we have loaded, set the folder deleted, as with the delete_folder case. svn path=/trunk/; revision=13786
