Rfc2898DeriveBytes -- 1000 iterations
It is my hope that simply increasing the loading time in this fashion will prevent the fatal X error from occurring.
To be precise, it is Fatal IO error 11 -- resource temporarily unavailable.

Sadly, that one is out of my hands. All I can do is code around it. If Rfc2898 @ 1k does not fix it, I have another plan to prevent the orphaned lockfile -- timed writes to the lockfile and checking for a timeout instead of merely its existence.
