Bugfix against the issue reported yesterday in my checkin comment 'I am loathe to check in code with known bugs.'  The issue was that we crossed over the threshold of it taking < 2 seconds to encrypt a container.  Consequently, the expect-based timeout value of 2 was causing the encryption process to abort prematurely.  Now the timeout values have been changed to -1, meaning they should always wait until the operation has completed.
