> However, we could make an exception for C finalizers registered via
`Foreign.ForeignPtr`, and give these extra guarantees. This has been
requested before, and I think it would be a useful feature.
As far as I can tell, running finalizers promptly is ''essential'' to
efficient functional graphics programming on modern hardware. For
graphics, C-only finalizers (for graphics resource deallocation) would be
a perfectly fine restriction to live with.
Could we get C finalizers executed promptly? For instance, could they be
executed at the end of each GC cycle, rather than thread-enqueued?
