| Serialise output to the screen, so error messages etc. don't appear in the middle of the progress bar. Prepend a carriage return to output messages if the progress bar is being printed, to ensure they appear on separate lines. Also disable the progress bar if -info option is specified. |

| Disable progress_bar if [l]lsonly or [l]info options specified. Also add carriage return on TRACE and ERROR statements if progress_bar is being printed to ensure they appear on a new line. |

| Synchronise output between threads, so error messages etc. don't appear in the middle of the progess bar. Also ensure the progress_bar doesn't appear whilst the pre_scan is being peformed, or while the summary statistics are printed at the end of the unsquash. |

|
| Move the progress bar into its own separate thread. Also only update progress bar on the completion of a file write and after a 1/4 second if the progress bar hasn't been otherwise updated by the completion of a file write. This reduces the time and I/O overhead of progress bar printing. Also add a rotate for more visual indication. |

|
| Rather than make the rotator in the progress bar rotate every 1/4 second on the timeout of the pthread_cond_timedwait, rotate it using SIGALRM, this makes the rotate more uniform. |

| Remove cache_get_2() as it's no longer used. Remove code that waited for all fragments to be written to disk when a file with blocks (not just a fragment) was written (fragments cannot be written in parallel with a file with multiple blocks, as the file blocks have to be written contiguously). Instead when a file with multiple blocks is written, queue generated fragments, and write them after the file is written. This improves parallelism. |

| Fix bugs in remove_hash_table and remove_free_list. Change cache to grow only in response to readahead rather than grow to maximum cache size. Replace fragment pending code used to ensure fragments have been written to disk in get_fragment routine with cache lookup. Add flag to cache code to indicate that read_buffer blocks are to be immediately deleted rather than being retained in the cache because they will never be reused. |
