Pausing log file not thread safe

[phillebaba]

Describe what should be investigated or refactored

When printing credentials to the debug log the log file writer is paused temporarily to avoid writing the credentials to the log file. The way this is implemented is not thread safe, meaning the it is completely possible for the writer to be resumed if PrintCredentialTable is run in parallel.
