Comment (by DonMoir):

 It seems to settle somewhere around 11,200,000 entries. I stopped it at
 that anyway. If you take the size of the file which is 186,042,456 bytes
 divided by 11,200,000 then thats about an entry for every 16 bytes.

 While it's doing this, it's eating the CPU big time plus memory overhead.
 It's just not going to work for most people. The only way out is to trap
 interrupt_callback and just fail, but wish there was some other solution.

 I am testing this on my slower machine and there I can't let it complete
 since this computer will overheat and shutdown. Have not tested it on fast
 machine but whatever the case I can't let this happen.
