I was once at a Apple Developers' Conference--a *way* long time ago--and Iw ent to a session on debugging. At the beginning they put a slide saying that a well written program should be able to run for hours--even days!--without crashing. Seemed both radical and obvious.
Seems neither? I mean, I've seen old database systems with uptimes measured in years, and one that was approaching a decade at the time (and if it's still running then it's a few years away from a second decade). A well-written program won't crash. Period.
But regarding SQLAlchemy, that sounds like a Python-ism. You can't delete classes in Python. The closest you can get is that a class will be reaped by the interpreter when nothing references it (the reference count is reduced to 0). Exhaustively walking the chains of references is the only way to be certain that all references to the class are eliminated.
