The other thing that can bite you is just plain bad engineering from a
scaling perspective.
You are exporting a file. You must be doing that for a reason, and most
likely so some other process or person can read that file.
You are assuming that another process does not have that file open with an
exclusive lock 100% of the time. Another process has it locked equal to 100%
minus the times it has worked in the past. I am going to guess the whomever
is paying the bill to operate this process wants the quantities and amounts
to always have the exact right amounts 100% of the time, so should the
process.

Start over. It's almost 2014. Don't design systems like they are only going
to be run on a TRS-80 Model III
