The new command is ns_ictl (interp control)
Each interp has an epoch and when you grab an interp, this is supposed to be
checked, ns_ictl can be used to make sure that things are cleaned up or
initialized.
I don't have any examples however, but you can see some of it at work in the
use bin/init.tcl script. For instance, this script closes files when a
connection closes. Also look at nsd/tclinit.c to see how connection interps
are managed. Maybe this is the key issue: not all interps are managed the
same way.
Can you describe what you are trying to achieve and how you test to see that
it isn't working? It would be nice to see some working code/configuration to
supplement the documentation.
