Howdy!

I hope someone can explain this behaviour to me; The kernel seems to
make a stream port "un-rebindable" within 60 seconds after another
stream-server-process has had the port bound.
The easiest way to illustrate (with port/sysutils/socket):
Terminal one:           Terminal two:
socket -s 19191
                        telnet localhost 19191
^C
                        Connection closed by foreign host
socket -s 19191
socket: server socket: Address already in use

[wait 60 seconds]
...and socket -s 19191 will succeed again.

What is causing this? This behaviour causes my application to fail a
critical requirement and there must surely be something wrong with my
(aswell as socket(1)'s) interaction with the tcp/ip stack?

TIA,

 Bjorn
