Since function logging is enabled per-process, the trace flags are
shared by all instances of the nntps being used. If multiple nntps
have tracing enabled, the TraceFlags property should be set to
the same value for each nntp. Changing the trace flags for any one
instance of the nntp will affect the logging performed for all nntps
used by the application.
Warnings are generated when a non-fatal error is returned by a
Windows Sockets function. For example, if data is being written
through the control and an error indicating that the operation would
block is returned, only a warning is logged since the application
simply needs to attempt to write the data at a later time.
