Yes, I think that's reasonable. I imagine you wouldn't have to extend Fil-C very much to sneak some memory-mapped I/O addresses into your program, but maybe ha

Yes, I think that's reasonable. I imagine you wouldn't have to extend Fil-C very much to sneak some memory-mapped I/O addresses into your program, but maybe having the garbage collector pause the program in the middle of an interrupt handler would have other bad effects. Like, if you were generating a video signal, you'd surely get display glitches.
