When Webmin is started via /etc/webmin/start, a file
descriptor for the current terminal is retained. This
makes it impossible to install the Webmin Solaris
package via a script (for example, via Pythons
subprocess module). The fix is simple: just close the
temporary open file.
The problem has been verified on both Linux and
Solaris. It can be verified by running "lsof | grep
miniserv. 13284 root 3u CHR 136,27
/dev/pts/27 is the tty that executed /etc/webmin/start.
