Come to think of it, I'd suggest if you're interested in lookin into
such debugging tools to rather consider writing a gdb-image (subclass
of movitz-image), where the GDB remote protocol is used to interface
the (emulated) machine running movitz. This should be even less
complicated than porting the procfs stuff to linux, and has many
advantages: better portability (across lisps and OSes), works with
QEMU, Bochs, and even actual hardware if only some GDB stub support is
added to the movitz image.
