Re: Disk write in a "for" loop with RwMutex never happens

After a bunch of playing around I managed to determine that it is as 
simple as the mode.

exists(dbFileName) ? "r+" : "w+"


Will fix it.

Of course you shouldn't delete the file like that method is doing. It 
should probably reinitialize the FILE* descriptor.
