Hi,

I like the general idea.  Thanks.

Wouldn't it be better to put the rollback_lock_file() into the if clause 
when commit failed?

Besides, I think you can safely call rollback_lock_file(lock) on a 
committed lock_file, since the name will be set to "" by the latter, which 
is checked by the former.

But I am fine with the patch as is (have not tested it, though).

Ciao,
