But for nsv shared variables you *have* to stringify because Tcl objs
can not pass between threads.  Here your explicitly looking for thread
local, so stringifying would seem to be an unnecessary slowdown.

This isn't a cache, there's no eviction policy.

I don't see how ns_tlsthis isn't exactly equivalent to:

  set ::tcl_MyMache Whatever

which has the big advantage of keeping Tcl objects in object form.
