hi!

when a network stream is inspected on sbcl then i get this error:

The value NIL is not of type PATHNAME. [Condition of type TYPE-ERROR]

Restarts: 0: [ABORT] Return to sldb level 1. 1: [CONTINUE] Return from BREAK. 2: [TERMINATE-THREAD] Terminate this thread (#<THREAD "an httpd worker 21" {C7D69F9}>)

looking at swank.lisp it does check for (typep stream 'file-stream) but it is T for socket streams which probably is the root of the problem.

also note the strange printed representation of the socket stream, but i guess it's also an sbcl thing. maybe i should have written this to sbcl-devel...

hth,
