I was thinking that this could be pushed down into the C API. But I
don't know if this makes sense. More checking of how the ADP code
uses thread local caches for Tcl code needs to be done.
We could add a flags option NS_CACHE_THREAD_LOCAL or whatever to
Ns_CacheCreate(). Ns_CacheLock/Unlock could depend on this flag.
One thing I looked at is gathering stats in the thread local cache and
then periodically flushing them to some common structure. I think
there's an example of this in the cache code I posted to the SF
tracker.
Unfortunately you can't keep it completely in the C layer, as you'd
like to optimise Tcl by storing Tcl objects directly, rather than
stringifying them.
