Could someone tell me why the file object in Filesystem.Tar (or rather the tar object it resides in I'm guessing) isn't removed immediately.
sizeof(Stdio.get_all_active_fd());
(1) Result: 10
object f=Filesystem.Tar("../../test.tar"); sizeof(Stdio.get_all_active_fd());
(2) Result: 11
destruct(f);
(3) Result: 0
sizeof(Stdio.get_all_active_fd());
(4) Result: 11
Is it removed if you do a gc?

I can't see any obvious cyclic references. My tip is to use _locate_references() on the interesting objects.

Bad. Try again now.

Are you referring to Filesystem.Tar or _locate_references?
As for the information from _locate_references I think it's not that hard to weed out the interesting parts. It'd be really nice to have one that returned the located references in some kind of structure, though.

Now it works. Though I'd say there is a bit too much information to be of any direct help...

Now it works to use _locate_references on Filesystem.Tar and its subobjects.
