-- fix thread locks
-- optimize translated cache chaining (DLL PLT-like system)
-- fix thread stack liberation (use kernel 2.5.xxx CLONE_CHILD_CLEARTID)
-- fix x86 stack allocation
-- fix iret/lret restarting
+short term:
+----------
+- support variable tsc freq
+- cpu_interrupt() win32/SMP fix
+- USB host async
+- IDE async
+- debug option in 'configure' script + disable -fomit-frame-pointer
+- Precise VGA timings for old games/demos (malc patch)
+- merge PIC spurious interrupt patch
+- merge Solaris patch
+- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
+- config file (at least for windows/Mac OS X)
+- commit message if execution of code in IO memory
+- update doc: PCI infos.
+- VNC patch + Synaptic patch.
+- basic VGA optimizations
+- physical memory cache (reduce qemu-fast address space size to about 32 MB)
+- better code fetch (different exception handling + CS.limit support)
+- do not resize vga if invalid size.
+- avoid looping if only exceptions
+- cycle counter for all archs
+- TLB code protection support for PPC
+- see openMosix Doc 
+- disable SMC handling for ARM/SPARC/PPC (not finished)
+- see undefined flags for BTx insn
+- user/kernel PUSHL/POPL in helper.c
+- keyboard output buffer filling timing emulation
+- return UD exception if LOCK prefix incorrectly used
+- test ldt limit < 7 ?
+- tests for each target CPU
+- fix CCOP optimisation
+- fix all remaining thread lock issues (must put TBs in a specific invalid
+  state, find a solution for tb_flush()).
+- fix arm fpu rounding (at least for float->integer conversions)
+
+ppc specific:
+------------
+- TLB invalidate not needed if msr_pr changes
+- SPR_ENCODE() not useful
+- enable shift optimizations ?
+
+linux-user specific:
+-------------------
+- add IPC syscalls
+- handle rare page fault cases (in particular if page fault in helpers or
+  in syscall emulation code).
 - more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
   issues, fix 16 bit uid issues)
-- finish signal handing (fp87 state, more siginfo conversions)
-- verify thread support (clone() and various locks)
-- make it self runnable (handle self modifying code, relocate stack
-  and dyn loader)
-- fix FPU exceptions (in particular: gen_op_fpush not before mem load)
+- use page_unprotect_range in every suitable syscall to handle all
+  cases of self modifying code.
+- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
+- use kernel traps for unaligned accesses on ARM ?
+
+
+lower priority:
+--------------
+- int15 ah=86: use better timing
+- suppress shift_mem ops
+- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
+- optimize FPU operations (evaluate x87 stack pointer statically)
+- use -msoft-float on ARM
