Subject: [PATCH] The 2.2-Beta version doesn't have the brackets after the if
 statement. This has the effect of making every link a "passthrough" which
 means the TCP or UDP port won't be freed after link deletion -- so there
 could be eventual port exhaustion if the program were allowed to operate long
 enough.
