I can see two options:
1. You create a RAM disk and the contents will obviously be gone when=20
the system reboots or crashes.
2. You encrypt the data with a ephemeral key that will be lost on reboot=20
(e.g., kept in shared memory). When the system comes up and finds itself=20
unable to read the data, it will erase it.

That doesn't really have much to do with Cygwin or Windows - you can do=20
that on any system.
