thing I noticed that was kind of nifty in the new tcl sources is a
check to see whether a particular canvas has been loaded. Namely, variable ::loaded($mycanvas) which effectively (if I am not mistaken) generates a member in the global ::loaded array and which is exactly what I needed.Actually, this variable is a bad example as it does get deallocated
but ::yscrollsomething($mycanvas) and another variable for x axis to the
best of my knowledge does not get deallocated. So, I guess the question
remains hopefully relevant...Please advise.

Like many dynamic lnaguages, Tcl has garbage collection, so its not
really a big deal. Ideally variables would be 'unset', but I don't
think you'll get a memory leak if you don't.
