Do you have some other examples that really get used often?  I'd think
f_lineno's don't get used that often.

Will you give some thought to going to a tagged representation of
object references, and maybe a more traditional GC?  That way you
avoid a lot of memory traffic, and also don't have to adjust reference
counts every time you touch anything.

I think these would give a big performance boost, and also would also
simplify the C API.  It might be possible to supply a compatibility
layer to make the old C API still useable.
