Yes, but only for certain "known" types of Tcl objects.
You can't cache bytecodes thread-wide because they
contain literals and they are entered per-reference
in bytecode rep. Even my tsv "tricks" will not work.
Moreover, bytecodes get re-compiled when jumping interp
so this all bytecode caching stuff is really not something
I would do from the cost/gain perspective.

The only real practical caching of bytecodes is moving
more code into Tcl procedures and putting less code in
the page itself.
