Re: non-persistent storage?

I can see two options:
1. You create a RAM disk and the contents will obviously be gone when 
the system reboots or crashes.
2. You encrypt the data with a ephemeral key that will be lost on reboot 
(e.g., kept in shared memory). When the system comes up and finds itself 
unable to read the data, it will erase it.

That doesn't really have much to do with Cygwin or Windows - you can do 
that on any system.
