I have problems getting things GC:ed properly when using
continuations, which is a bit disturbing.
I was looking at a few implementations of coroutines and they seem to
prevent their continuations from being gc:ed.
For example, I looked at this implementation:
http://onestepback.org/articles/invitationtoruby/coroutinedemo.html
Altering the end of this demo to do:
first.start
first = nil
second = nil
garbage_collect
ObjectSpace.each_object(Continuation) {|x| puts x }
Gave me a list of all the continuations spawned by the two
coroutines. Apparently they had yet to be GC:ed. Another
implementation seemed to be similarly flawed.
Is there a way to make this work or perhaps my understanding of the
GC is flawed?
Sincerly,
Christoffer
