2.01 [KK 2008-08-08] Implemented flag -C (--close-sockets-fast): this
option *can* be used under heavy stress when too many network sockets
remain in TIME_WAIT state (try with 'netstat -n | grep TIME_WAIT').
Syntax of xrctl is checked upon "make commit".
Added documentation about Solaris tcp_time_wait_interval and Linux
ip_conntrack_max.
Added documentation about binding XR to the same port, using different
bind-to IP's.
