I imagine ns_eval "package forget whatever" would probably work, but I
don't really use package, so you'd have to try it.

What do the other aolserver programmers do to ask all the tcl interps
to reload, so that new code can be brought in without restarting the

I have a technique (described below) but it's not bug-free, so I was
wondering what people recommended?
One possibility, would be to ask all the tcl interpreters to exit on
the next page request, so that a new thread and thus new tcl
interpreter is created, loading up the new libraries. I don't know
how to do that, though.
Currently, I have a namespaced global variable $reload::time that is
set to the time when the last "package forget/package require". was
run When I want to reload all interpreters, I set a nsv variable to
the current time, and a function registered as
ns_register_filter postauth GET /* mooch_reload_check
runs for every page, so that if the nsv's reload time is not the same
as the local interp's reload time, then I run:
foreach p [package names] {
package forget $p
}
This seems to mostly work, but some interpreters don't play nice.
Other suggestions.... ?

I use ns_eval {source the_tcl_file} which only works for one file at a
time, but seems to make sure the files are reloaded in every
interpreter including scheduled procedure threads. Reloading in a
filter does not work for scheduled proc threads. OpenACS has this
technique that reloads changed files in a registered filter, but it
suffers from the same problem that occaisionally the files are not
reloaded into the interpreter.
