Re: How to safely maintain a status file

[Laszlo Nagy]

    Renaming files is the wrong way to synchronize a
crawler.  Use a database that has ACID properties, such as
SQLite.  Far fewer I/O operations are required for small updates.
It's not the 1980s any more.
I agree with this approach. However, the OP specifically asked about 
"how to update status file".
