Stale pid file with same pid preventing amavis startup

I'm running FreeBSD 10.3, with amavisd-new 2.10.1, in a VM.

I experience an issue where amavis startup is aborted if the pidfile 
already exists and contains the same pid as the newly started amavis 

After an unclean shutdown of my VM, the system is starting up and amavis 
receives the same pid as last time it was booted.
When the stale amavis pid file contains the same PID as the newly 
started process, it aborts.

/usr/local/sbin/amavisd at amavisd-new-2.10.1 (20141025),

# ls -la /var/amavis/
-rw-r-----  1 vscan  vscan  4 Jul 23 05:04 /var/amavis/
# cat /var/amavis/

Starting amavis manually, with a new PID, is working fine. I did not 
have to remove the old stale pid file.

Is this something which can be, or has been, solved in amavis, or do you 
recommend I work around this by removing any stale PID file during boot, 
before amavis is started?
