Currently this isn't possible - if you attempt to open
System.Memory("/dev/some-device") it rejects it due to being unable to
query the length of the file. It would be nice to be able to, for
example, stick Pike on a Raspberry Pi, and then mmap /dev/gpiomem to
manipulate things. Would it be of value to have a way to bypass that
length check? I think that that's the only thing stopping it, although
I'm not entirely certain.
