Yes, this has been reported a few times now. The only case where the
lock would not work is if there were several instances of the
LocalStatusFolder representing a single folder or pointing to the same
filename, which is something that should not happen at all. 

So using a global lock would certainly paper over some real bug, obviously.

I never see these errors, so I have a hard time reproducing this. Could you
find out if there are several LocalStatusFolder instances created for
the same folder for you?

Some help would be appreciated in this case :)
