  79 Quoth Justus Winter on Mar 21 at  1:55 am:\r
  80 > I propose to split the function notmuch_database_close into\r
  81 > notmuch_database_close and notmuch_database_destroy so that long\r
  82 > running processes like alot can close the database while still using\r
  83 > data obtained from queries to that database.\r
  84 \r
  85 Is this actually safe?  My understanding of Xapian::Database::close is\r
  86 that, once you've closed the database, basically anything can throw a\r
  87 Xapian exception.  A lot of data is retrieved lazily, both by notmuch\r
  88 and by Xapian, so simply having, say, a notmuch_message_t object isn't\r
  89 enough to guarantee that you'll be able to get data out of it after\r
  90 closing the database.  Hence, I don't see how this interface could be\r
  91 used correctly.\r
  92 \r
  93 Maybe you could describe your use case in more detail?\r
