I'm not sure what you mean with "real memory" or how precise you want that 
measurement to be, but you could try http://www.selenic.com/smem/
(and, within Python, re-use smem's concepts, which shouldn't be too difficult)

Again, not sure what you mean with "allocated to variables" (global variables? 
local variables? everything?). As for "re-capturable data not yet GC'd", the
best way to figure out is to run gc.collect() :-)
