Why do you assert! if the thread is panicking in your Drop implementation?

For the Drop implementation of Secret<T> (linked above), why do you assert if the thread is panicking when the target is not on Windows and munlock was successful?

My purpose is to understand and learn from you.

Thank you.

The comments say that attempting to munlock() a second item on the same page on Windows is expected to return an error, and is being ignored.

As I read it, the code says that if munlock() failed and this isn't on a Windows system (and the last OS error code was 158), then that's a problem (ie. we must panic) unless we're already panicking.
