Is this a bug? Python intermittently stops dead for seconds

[charlie strauss]

Steve, digging into the gc docs a bit more, I think the behaviour I am seeing is still not expected.  Namely, the program I offered has no obvious place where objects are deallocated.  The way GC is supposed to work is thate there are three levels of objects

level0:  newly created objects
level1:  objects that survived 1 round of garbage collection
level2:  objects that survivied 2+ rounds of gargbage collection

Since all of my numerous objects are level2 objects, and none of them are every deallocated, then I should never trip the GC for these.

Your explanation would require this to be tripped so I can't explain it.  For your explanation to be correct then there as to be some non-obvious step in the program that is deallocating level2 items in sufficient numbers to trip the GC.
