As far as I know yes - reverse.
so trace plugin is unloaded before UnloadDetectorHelper in the engine is fired.
In this case the engine's UnloadDetector must not call routines from other libraries.
Why do you think it does ? Do you have a stack trace ?
Does your embedded app calls fb_shutdown() before exit() ?
Does your dll module conains code that detects "unxpected" unload (as
UnloadDetectorHelper do) ?
Does your dll module run cleanup code in this case ?
