The specific problem with SLIME is that if *print-readably* is true, then the communication between Emacs and the Swank server in the repl thread throws an error during initialization. This is because in the process of setting up a connection, the character encoding needs to be specified and when this encoding spec is written to the connection stream, it cannot be written "readably" and an error is thrown by prin1.
So SLIME is expecting a certain behaviour (*print-readbly* being false) in a newly spawned thread. Whether this expectation is correct or not, I have no idea but I presume it is reasonable as Gary stated in his earlier email.
There is a mechanism in SLIME (currently unused) to bind variables prior to thread creation so one could conceivably bind *print-readably* to nil prior to a new worker thread being spawned if the CL implementation was setting it to t (it wouldn't affect any other CL implementation either). However, I thought this was a simple mistake (CCL behaviour changed and I hadn't read the spec on with-standard-io-syntax at that point) which is why I asked the question.
