Comment (by stephen):

 First off, what is the logging configuration for each of these problems?
 I'm guessing that this is logging to a file as syslog should force log
 messages to be sequential.

 For the first and third examples, my guess would be that it is due to the
 Python logging to stdout and having no flush set.  However, the second
 example - where messages from different components b10-auth appear to be
 interfering with each other - is a puzzler.  If there is no separate
 configuration for the "auth" and "cc" logger in the b10-auth program, they
 should all be logging through the same stream: as the code is single-
 threaded there should be no chance of interference between two log
 messages.  It makes me wonder if what we are seeing is some buffer
 corruption in the logger or log4cplus.
