Having a socket in Close/Wait for an extended period of time is the result of
bugs in the kernel, either on your end or on the other end. There is nothing
you can do about it, but it should not be harmful either. Kernels can handle
tens of thousands of socket connections, and connections in Close/Wait do not
count towards the per-application socket limit, so applications should not be
affected. (Contrast Close/Wait to Time/Wait, which is completely normal,
necessary, not the result of bugs, and only last for a minute or so).
All of this is unrelated to REBOL or any modes/options set in REBOL.
