enabled. Otherwise, it does nothing. The message is thread safe,
therefore providing that the messages appear in the order they where
issued by the different threads.
All messages are suppressed when Debug is false. All messages with a
lower importance (higher number) than DebugLevel will be suppressed,
too. Debug level 0 messages will always be printed as long as
Debug is true.
We use our own debugging method, since debugging threads is a more
complicated experience than debugging single threaded
contexts. This might change in future in the way that debug
prints its messages to another logging facility provided by
the platform.
Use setDebugLevel () to integrate adapt debug () to your platform.
