> When we have a Table with {{low=40, hd=40, hr=45}} and receive a {{purge(30,true)}}, then the table will be {{low=30,hd=30,hr=45}}.
> This only happens with parameter {{force}} being {{true}}.
> This doesn't cause any bugs, but until the next (correct) {{purge()}} is invoked, the table will show and incorrect number of missing messages.
> SOLUTION: add the check to the start of {{purge()}}:
> {code}
> if(seqno <= low) // perhaps check for force as well
>     return;
> {code}
