Yes, you need to read the docs:
http://aolserver.com/docs/devel/tcl/
http://aolserver.com/docs/devel/tcl/tcl-general.html
Well, hm, those oldish docs aren't quite as clear as they could be.
But anyway, the main point is:
Tcl globals are per-thread in AOLserver, NOT server wide. If you need
a server-wide variable, use nsv instead.
Don't feel too bad, this is a very typical mistake for people to make
when new to AOLserver, until they read and remember the docs on how
the basics of multi-threaded Tcl in AOLserver works. :)
