server may fail to accept any client connections.

The reason is that the mysql_connect() has no timeout ability - it can just hang if the server is 
unresponsive.

Ideally we should detect this and continue without audit, but then fail to do anything (audit db cannot be 
contacted.

This should be a low priority.  Different audit db's may behave wildly differently.
