Hi Sergey, 

Good catch, I added the memsets to the two other files, too.
Sorrry it took that long, I just wanted to make sure it causes
no upsets on solaris or BSD, I had to fix our build first.

New webrev:

This ran through all our testing successfully.  I'll push it Monday
to client if there are no objections.

Best regards,
