OpenARC 0.1.0 memory leak?

[Jered Floyd <jered@xxxxxxxxxxxxx>]

Before I try to debug this, I was wondering if we were aware of a memory leak in OpenARC-0.1.0. It has been consuming an increasing amount of memory on my system, and is disproportionate to the similar OpenDKIM: 

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND 
opendkim  9894  0.0 53.6 1570348 1096412 ?     Ssl  Jan18   7:25 /usr/local/sbin/openarc -c /etc/openarc.conf 
opendkim 29899  0.0  0.5 690144 11228 ?        Ssl  Feb18   1:46 /usr/sbin/opendkim -x /etc/opendkim.conf 

Signing mode only, my openarc.conf is below.
