I saw exactly the same behavior on AIX (Unix for the IBM RS-6000) in
the early '90s. At that point it was explained to me that this delay
before a port can be reused is intentional. It is designed to prevent
any packets which are already in transit when the port gets closed
from causing problems. If a new socket opens immediately with the same
port number, these pokey packets will show up at that socket
unexpectedly. There is a small but finite chance that they will be
interpreted as valid packets. Of course, a packet could theoretically
be delayed for hours, but the timeout of 30 seconds or so was
considered long enough to reduce the chance of error to an acceptable
level.
