* Rewrote vCtdlLogPrintf() to NOT use any buffers at all, only v*printf() type functions.  We do this by writing the log data and metadata in separate calls.  In practice, this will cause them to appear on the same line even when other threads are concurrently writing because we are using buffered I/O.  Unfortunately, this does NOT fix the server crash that occurs when saving instant message transcripts to disk.  It points us in the right direction, though.
