Extended Example: Event Log File
================================

Many concurrent systems use a common log file to store records of key events.
For instance, journaling file systems use a log to keep track of changes that
can be validated in case of a system crash. This Extended Example uses multiple
threads that create random fake events that then get written to the common log
file. Access to the log file is synchronized to ensure that the writes do not
interfere with each other.
