Bug#746511: sasl2-bin: memory leak

[Andreas Edler]

Package: sasl2-bin
Version: 2.1.23.dfsg1-7
Severity: important

Over time saslauthd will grab more and more "apps memory", and it appears
it never frees it up again.

Find attached a memory usage graph.  The drops in usage are a result of
restarting saslauthd only, nothing else has been done at these times.
