* Guardians:
- clean up after file ports are dead by flushing/closing the
underlying file handle.
* Interrupts:
- pcb should have an engine-counter field that's decremented on
every procedure call.
- an engine-expired procedure must be called when the counter goes
negative. It should capture the current continuation and
reschedule the process.
- figure out what to do when a process gets interrupted while
reading from a file.
- Implement [CTRL-C] keyboard interruption with the ability to
resume the computation, reset to the repl, or terminate the
program (at least for now).
* FFI:
- provide a general mechanism for calling foreign procedures
without having to extend the VM.
(foreign-call void: FOO int32: x char*: y ptr: z)
- may dump the bignum stuff in the VM and move it to scheme.
