No, cmd is a module that provides a line-oriented command interpreter
for console, nothing to do with TK.

But one would think it's reasonably safe to access a resource one
thread at a time, via mutexes etc. (and some external resource, such
as sockets, almost *have to* be accessed in multiple threads). Is TK
really such a beast that all the access to TK widgets have to be
called via it's own event loop?
