going to do when it dies? I'd love if Pd would provide some true
multi-threading (not like [pd~] which is tightly coupled to its parent).

That's a clever point I'm also sharing, but from informations grabbed in tcl documentation
that seem to imply a complete rewrite of the client:

Some consolidated rules for embedding Tcl in a threaded application:

• You can NEVER use the same interpreter from more than one thread

• If you only have one Tcl Interpreter:

• You can use either Unthreaded or Threaded Tcl

• No Big Global Mutex [Big Global Mutex] is required for Unthreaded Tcl Build (Never required for Threaded Tcl build)

• If you have Multiple Tcl Interpreters:

• If you are using an Unthreaded Tcl Big Global Mutex [Big Global Mutex] is required for ALL calls to functions in libtcl

• If you are using a Threaded Tcl, no mutex locks are required
