Changes in version 1.1.0 (2019-03-08)                  

  - Work around a SQLITE bug that resets the database busy timeout after
    a successful query. Now we set the timeout after each database
    operation. The timeout can now also be set via the
    R_LITEQ_BUSY_TIMEOUT environment variable, and it defaults to 10
    seconds, instead of 1 second.

  - consume() now has a poll_interval argument to set how often to poll
    the queue for new jobs.

  - New is_empty() and message_count() functions (#18, @wlandau).

  - Get rid of annoying warning about closing unused connections (#15,
    #20, @wlandau).

                 Changes in version 1.0.1 (2017-10-20)                  

  - Set the LITEQ_CACHE_DIR environment variable to change the default
    cache directory.

                 Changes in version 1.0.0 (2017-01-27)
