Hi all,

I'm trying to understand why this simple script doesn't trigger a single run of the GC and eats all memory:

```Ruby
require 'gdk3'

loop do
  Gdk::Pixbuf.new('foo.png')
end
```

Changing it just a little to print ```Ruby GC.stat[:count]``` shows a constant value always:

```Ruby
require 'gdk3'

i = 0
loop do
  i += 1
  Gdk::Pixbuf.new('foo.png')
  puts GC.stat[:count] if (i / 100).zero?
end
```
Moreover, if I manually run it, then the memory usage stays constant:

```Ruby
require 'gdk3'

loop do
  Gdk::Pixbuf.new('foo.png')
  GC.start
end
```

I understant that this is probably a gdk3 issue, but what is puzzling me is why GC isn't running automatically but if I start it manually everything works just fine.

Thank you!
