Title:
  simple-scan allocates memory for one page (possibly a lot) on startup

Status in Simple Scan:
  Triaged

Bug description:
  1. Begin a scan at a high resolution. Observe memory usage.
  2. Kill simple-scan (using "killall simple-scan" from a terminal)
  3. Restart simple-scan. Observe memory usage.
  4. Lower resolution (Documents → Preferences) and begin a new scan. Observe memory usage.

  I ran into this problem after (ambitiously) trying to scan a full A4
  page at 1200 dpi on a machine with only 1 GB RAM (bad idea). Once
  memory usage hit ~97%, I gave up and killed the application.

  However, everytime I would restart it afterwards, it would
  *immediately* grab almost as much memory. I tried clearing the
  contents of ~/.cache/simple-scan, as well as some .tiff files I found
  in /tmp, to no avail.

  The memory usage didn't drop until I performed steps 3 and 4 as
  explained above.

  $ apt-cache policy simple-scan
