TODO

--- Legend:
 [-] not yet done
 [+] done
 [*] in progress

--- General:
+ Cleanup read vs load.
- Cleanup static functions.
- Cleanup header usage.
- Cleanup error handling (abort cleanly to the process in question too).
- Cleanup verbosity/debugging messages.
- Check use of malloc in restore funcs.
- Licensing on each file.
- Do a better malloc implementation (even if it involves beating libc malloc to
  not use mmap somehow).
+ Better remote syscall support, ala _syscall{0..5}.
+ Split out write vs read code. Why isn't the linker smart enough to do this?
+ Figure a sane way of building & linking against uclibc or dietlibc.
- Implement make-static cleanly.

--- Misc:
- Environment
- Command line
  If randomize_va_space = 0, then we should be able to reconstruct the
  environment, argv, and obtain the right offset.
  Otherwise, if we're probably screwed.
- Working directory

--- Registers:
+ regs
+ fail syscalls in progress with EINTR (are there any we should restart?)
+ restore after getting image

--- FPU:
- i387 state

--- TLS:
+ TLS segments
+ tls hack for porting 2.6 processes to 2.4

--- File descriptors:
+ files
- file contents
+ fcntl state - blocking & close_on_exec
- fcntl state - locks
+ consoles
+ termios state
+ TCP sockets
- allow for not killing TCP sockets when saved
- tcpcpd to firewall TCP connections when being migrated
- UDP sockets
+ Unix sockets
+ FIFOs to self
- FIFOs to other processes
- sound devices (ALSA & OSS)
- large file support
+ deleted files (scrape out and regenerate)
- interactive prompting for file seek offsets and restoration

--- VMAs:
+ memory segments
+ un-mprotect unreadable segments so they can be scraped.
- detect EIO and claim VM_IO, so just mmap it on other side.
- deal with non-existant VMAs... warn before continuing?
+ Checksum unsaved libraries
- Allow turning checksums off for speed.
+ mmap existing libraries if available, even if in image, to save on memory

--- Signal Handlers:
+ sighands
- process signal masks (blocked, ignored)
+ stopped state
- restart alarms
+ SIGWINCH me

--- IPC:
- shared memory
- semaphores
- message queues

--- Threads:
- Identify common:
  - CLONE_PARENT
  - CLONE_FS
  - CLONE_FILES
  - CLONE_NEWNS
  - CLONE_SIGHAND
  - CLONE_THREAD
  - CLONE_VM
- TLS
- TID
- futexes

--- Compression:
+ LZF
- LZF in-place decompression
+ GZIP


--- Graphics:
+ Gtk hooks
