Random data point: I appear to have been running with '-y' on for many 
weeks currently and for multi-month stretches prior to that as a result 
of some troubleshooting with Postfix something like a year ago, and have 
never noticed any memory leakage or CPU hogging as a result. I literally 
turned it on in troubleshooting and forgot about it, forgetting about it 
and never noticing it as an issue. The  version of libmilter MD uses is 
8.15.2 and I *THINK Postfix uses the same version, but it's statically 
linked and I can't tease out a version.
