Threads require a degree of programming care that even a crash-safe language like Python can't always protect you from. Combining it with garbage collection is a well-know trouble-spot in other languages too.Collaborator Czaki commented Nov 29, 2023 Python in it's documentation clearly ...
Avoid pitfalls in Python memory management As noted, objects can pile up in memory and not be collected if you still have references to them somewhere. This isn’t a failure of Python’s garbage collection as such; the garbage collector can’t tell if you accidentally kept a reference to ...

A third generation closely related to thetenuredgeneration is thepermanentgeneration. Thepermanent generationis special because it holds data needed by the virtual machine to describe objects that do not have an equivalence at the Java language level. For example objects describing classes and methods ...
Implementations like Python, which use both systems, suffer from both penalties. These issues reduce the suitability of garbage-collected languages for cases where performance is critical, or real-time applications are necessary. One can see the performance penalty in action even on these toy ...
The primary criterion for an object to be collected by the garbage collector is the absence of any active threads that retain direct or indirect references to the object. In this context, explicitly assigning null to a reference does not directly influence the garbage collection process, as the ...

Minor collections can be optimized assuming the weak generational hypothesis holds and most objects in the young generation are garbage and can be reclaimed. The costs of such collections are, to the first order, proportional to the number of live objects being collected; a young generation full ...
The LISP language had the first garbage collector back in 1959. Since then many languages like Java have adopted Garbage collection for automatic memory
A softly reachable object may be garbage collected at the discretion of thegarbagecollector. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The problem of lacking registers was solved by a new conservativegarbagecollector. ...
