Detailed Description

This class sets up null TSS SSL state upon instantiation, and restores the previous TSS SSL state when that instance goes out of scope.

This guard is used to make TSS SSL state configuration and deconfiguration during an upcall exception safe. Exceptions are not supposed to be propagated up to the scope this guard is used in, so this guard may be unnecessary. However, since proper TSS SSL state configuration/deconfiguration is critical to proper security support, this guard is used to ensure that configuration/deconfiguration is exception safe.
