I've left my project running all day and overnight, with no apparent change in any of the response or memory conditions.
After using Blitz for nearly 3 years I'd forgotten what it was like to have such concerns (ahh, the good old days of other languages - not!)
Mind you, pehaps Windows has memory fragmentation problems, but that's a different matter.
Just make sure that you don't get caught out (as I have been) by not releasing resources; or every time you do something (e.g. enter a screen) you recreate them (using twice as much memory) using the same variable (so it's not apparent).
