Some peculiar behaviour has crept into Webmin between 1.290 and 1.330.  In 1.330, whenever I issue a 'service webmin start' command, I get a new instance of even if there was one already running.  Do it again, and I get another one.  I am using Red Hat EL3 and EL4.
In 1.290 and previous versions, there would only be one instance of running, no matter how many times you issued a service webmin start command.
I dug into this some more, and discovered that in the earlier version, when a second instance of was started, it would fail to bind to the port and die.  In the latest version, when initially fails to bind to the port it reports the error and then tries to bind to the same port on INADDR_ANY.  If this fails the error is simply stored (not reported) and processing continues. 
Is this a bug, or is there a configuration detail that I am missing?
